I'm Trying to make a get Request
[HttpGet]
public async Task<IActionResult> GetOrders()
{
int marketingId =
int.Parse(User.FindFirst(ClaimTypes.NameIdentifier).Value);
var orders = await _repo.GetMarketeerOrders(marketingId);
var ordersToReturn = _mapper.Map<IEnumerable<MarketeerOrdersDto>>
(orders);
return Ok(ordersToReturn);
}
and this is GetMarketeerOrders Function
public async Task<IEnumerable<OrderDetails>> GetMarketeerOrders(int id)
{
var orders = await _context.OrderDetails.Include(i =>
i.Option).ThenInclude(i => i.Product).Include(i => i.Order).ThenInclude(i =>
i.Bill).Where(i => i.Order.MarketingId == id).OrderBy(i =>
i.Order.OrderDate).ToListAsync();
return orders;
}
but it throws the following exception when making the request, in my case I'm using Swagger UI
System.NullReferenceException: Object reference not set to an instance of an object.

It comes to this line of code when debugging
int marketingId = int.Parse(User.FindFirst(ClaimTypes.NameIdentifier).Value);
Then it stops and throws the exception
But when using the same request from the client-side using angular and subscribe it by storing the response into some variable like this
ngOnInit(): void {
this.marketeeerOrdersservice.getOrders().subscribe(d =>{
this.allOrders = d;
});
}
and this is the getOrders Method
getOrders(){
return this.http.get<MarketeerOrders[]>(this.url);
}
Then there is no problem at all
What is the reason I can't figure it out
Is it because I should always store the response in a variable ?
I don't think so because other requests work properly without having to do this
The issue is that LocalStorage where i've stored my token is a frontend concept. It is accessible to JavaScript running in the browser. asp.net resides on backend and can not access the LocalStorage directly.
You'd need to access it through the scripts running in frontend which can communicate with backend using Ajax requests.

I have created an OSS bucket and I'm trying to upload a file to it, but getting an error every time. Here is my bucket:
{
"dictionary": {
"bucketKey": "-removed my client id-------------test1",
"bucketOwner": "-removed my client id------------",
"createdDate": 1661180310185,
"permissions": {
"dictionary": {
"0": {
"dictionary": {
"authId": "-removed my client id------------",
"access": "full"
},
"count": 2
}
},
"count": 1
},
"policyKey": "temporary"
},
"count": 5
}
When I try to upload a CAD file to the bucket, I get an error as shown below. I have created a few buckets with another app, and even gone so far as to remove my old app and create a new one. Same issue.

Pretty sure this isn't a Scope issue, as scope is set as shown below:
public static async Task<dynamic> GetInternalAsync()
{
if (InternalToken == null || InternalToken.ExpiresAt < DateTime.UtcNow)
{
InternalToken = await Get2LeggedTokenAsync(new Scope[] { Scope.BucketCreate, Scope.BucketRead, Scope.BucketUpdate, Scope.BucketDelete, Scope.DataRead, Scope.DataWrite, Scope.DataCreate, Scope.CodeAll });
InternalToken.ExpiresAt = DateTime.UtcNow.AddSeconds(InternalToken.expires_in);
}
return InternalToken;
}
Please check two things:
that your code is generating the token for the same Forge Client ID that owns the bucket
that your Forge subscription is valid (if it's a trial, perhaps it has expired?)
And if none of the above helps, please share your Forge Client ID and the name of one of the problematic buckets with us via forge (dot) help (at) autodesk (dot) com.

// This makes development on mac easier.
.WithMacKeyChain("app_context", "user_token")
.Build();
var cacheHelper = MsalCacheHelper.CreateAsync(storageProperties).GetAwaiter().GetResult();
cacheHelper.RegisterCache(_app.UserTokenCache);
}

var accounts = await _app.GetAccountsAsync();
if (accounts.Any())
try
{
// Attempt to get a token from the cache (or refresh it silently if needed)
result = await _app.AcquireTokenSilent(scopes, accounts.FirstOrDefault())
.ExecuteAsync();
}
catch (MsalUiRequiredException)
{
}
// No token in cache, attempt device code flow
if (result == null && interactive)
result = await GetTokenForWebApiUsingDeviceCodeFlowAsync(scopes, deviceCodeCallback);
return result;
}
private async Task<AuthenticationResult> GetTokenForWebApiUsingDeviceCodeFlowAsync(IEnumerable<string> scopes,
Action<DeviceCodeResult> deviceCodeCallback = null)
{
AuthenticationResult result;
try
{
result = await _app.AcquireTokenWithDeviceCode(scopes,
callback =>
{
if (deviceCodeCallback is not null) deviceCodeCallback(callback);
return Task.FromResult(0);
}).ExecuteAsync();
}
catch (MsalServiceException ex)
{
throw;
}
catch (OperationCanceledException)
{
result = null;
}
catch (MsalClientException ex)
{
result = null;
}
return result;
}
The error indicates to me that it's a configuration error on my part but it why would it work outside of an docker environment.
I am a bit lost on this one and any help is greatly appreciated.
I found the problem. The app registration in my b2c was not configured to allow public client authentication.
The switch controlling that setting
The authentication code worked after changing that value.
I have a repository for albums table (album entity) and I do filtering and paging in repository as you see:
public IQueryable<Album> GetAllAlbums(AlbumQueryParameters queryParameters)
{
var albums = _cache.Get<IQueryable<Album>>("_AllAlbums");
if(albums == null){
albums = _context.Albums;
_cache.Set<IQueryable<Album>>("_AllAlbums", albums, ApplicationDefaults.MemoryCachingOption);
}
if(queryParameters.ArtistId != null)
{
albums = albums.Include(a => a.ArtistToAlbums)
.SelectMany(a => a.ArtistToAlbums)
.Where(a => a.ArtistId == Convert.ToInt32(queryParameters.ArtistId))
.Select(a => a.Album);
}
if(queryParameters.GenreId != null)
{
albums = albums.Include(a => a.AlbumToGenres)
.SelectMany(a => a.AlbumToGenres)
.Where(a => a.GenreId == Convert.ToInt32(queryParameters.GenreId))
.Select(a => a.Album);
}
// Pagination
albums = albums.Skip(queryParameters.Size * (queryParameters.Page - 1))
.Take(queryParameters.Size);
return albums;
}
And here is my controller:
[HttpGet]
public async Task<IActionResult> GetAllAlbums([FromQuery] AlbumQueryParameters queryParameters)
{
var albums = _albumRepository.GetAllAlbums(queryParameters);
return Ok(await albums.ToListAsync());
}
When I try to get data from this action I get this error:

And when I comment the Pagination I get a new error:
System.ObjectDisposedException: Cannot access a disposed context instance. A common cause of this error is disposing a context instance that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling 'Dispose' on the context instance, or wrapping it in a using statement. If you are using dependency injection, you should let the dependency injection container take care of disposing context instances.

I don't know what to do to fix my problem.
The first exception happened when Skip and Take is zero, so you can check it before add pagination to query:
if(queryParameters.Size>0)
albums = albums.Skip(queryParameters.Size * (queryParameters.Page - 1)) .Take(queryParameters.Size);
The second exception is about object life time you add ApplicationDbContext as Scope means it lives in request life time but you add IAlbumRepository as Transient means a new instance is provided to every call interface so when you call this line:
var albums = _albumRepository.GetAllAlbums(queryParameters);
One instance of IAlbumRepository created and when respond and return albums, it will disposed and any objects in it will disposed (includes ApplicationDbContext), for prevent this exception just add IAlbumRepository as Scoped like this:
services.AddScoped<IAlbumRepository, AlbumRepository>();
I think it's better to return List instead of IQueryable some thing like this:
public async List<Album> GetAllAlbums(AlbumQueryParameters queryParameters)
{
//do some stuff
return await ablums.ToListAsync();
}
And in the controller:
return Ok(await _albumRepository.GetAllAlbums(queryParameters));
I have the following ConfigureServices() content in my Startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
services.AddDbContext<GMContext>(options =>
{
var myConnectionSettings = Configuration.GetSection("ConnectionSettings").Get<ConnectionSettings>();
var sshSettings = myConnectionSettings.SSH;
var databaseSettings = myConnectionSettings.Database;
string keyFilePath = Path.Combine(Directory.GetCurrentDirectory(), "test4");
var authMethods = new List<AuthenticationMethod>
{
new PrivateKeyAuthenticationMethod(sshSettings.UserName, new PrivateKeyFile(keyFilePath))
};
using (var sshClient = new SshClient(new ConnectionInfo(sshSettings.Server,
sshSettings.Port, sshSettings.UserName, authMethods.ToArray())))
{
sshClient.Connect();
var forwardedPort = new ForwardedPortLocal(databaseSettings.BoundHost, databaseSettings.Host,
databaseSettings.Port);
sshClient.AddForwardedPort(forwardedPort);
forwardedPort.Start();
MySqlConnectionStringBuilder csb;
csb = new MySqlConnectionStringBuilder
{
Server = databaseSettings.BoundHost,
Port = forwardedPort.BoundPort,
UserID = databaseSettings.UserName,
Password = databaseSettings.Password,
Database = databaseSettings.DatabaseName
};
options.UseMySQL(csb.ConnectionString);
}
});
I then pick up the context in a controller and attempt to query the context I get a connection denied error:
namespace CoreGMWebAPI.Controllers
{
[Produces("application/json")]
[Route("api/[controller]")]
public class CropController : Controller
{
private readonly ILogger<CropController> _logger;
private readonly GMContext _context;
public CropController(ILogger<CropController> logger, GMContext context)
{
_logger = logger;
_context = context;
}
/// <summary>
/// Gets a Sample Items
/// </summary>
/// <returns></returns>
[HttpGet]
public async Task<List<TCountries>> GetSampleItems()
{
var result = _context.TCountries.Take(10).ToList();
return result;
}
}
}
The Error:

When I run the following quick test inside the ConfigureServices() method in Startup.cs it connects and queries without any issues:
...
options.UseMySQL(csb.ConnectionString);
var otherOps = new DbContextOptionsBuilder<GMContext>();
otherOps.UseMySQL(csb.ConnectionString);
using (var context = new GMContext(otherOps.Options))
{
var testRun = context.TCountries.Take(3).ToList();
}
This leads me to suspect that the SSHClient is closing before the Controller can use the dbContext. Should I somehow be passing the SSHClient as well as the dbContext? Any help would be appreciated.
I have two get statements in a controller
[HttpGet("{projectId:int}")]
public async Task<ActionResult<Models.Project>> GetById(int projectId)
{
var project = await _context.Projects.FindAsync(projectId);
if (project == null)
{
return NotFound();
}
return project;
}
// GET: api/project/5
[HttpGet("{projectCode}")]
public async Task<ActionResult<Project>> GetProjectByProjectCode(string projectCode)
{
var projects = await _context.Projects.FindAsync(projectCode);
if (projects == null)
{
return NotFound();
}
return projects;
}
The first get works perfectly and does what it is supposed to do pass in an ID and return the project associated with that ID
The second get does not work like it is supposed to. What it is supposed to do is pass in a projectCode parameter (string) and return the project associated with that project code.
The project codes are formatted like this --7000316139.13.01-- so that is why I am passing it using a string parameter
When I run the api with swagger I get the following error
System.ArgumentException: The key value at position 0 of the call to 'DbSet.Find' was of type 'string', which does not match the
property type of 'int'. at

I am not sure what the error is and why it is happening?
I have tried to switch the GetProjectsByProjectCode to public IActionResult but that did not help either
As ChiefTwoPencils pointed out the issue here is the primary key is an int and I am passing a string. I think I should probably get some sleep
