Error when trying to connect using SSL with AWS RDS. Cannot read the pem certificate

Context
I am trying to connect to postgres instance in AWS using the certificate suggested by AWS to make that kind of connection possible. But I cannot process the pem file because it is trowing and exception related with System.Security.Cryptography. I try to use the same logic you are using here to reproduce it faster: https://github.com/npgsql/npgsql/blob/3d41e7b629d727349218226a0f99489e6ffa05bb/src/Npgsql/Internal/NpgsqlConnector.cs#L747
and I am getting the same result.
Steps to reproduce
config = {
"SslMode": "Require",
"TrustServerCertificate" : true,
"SslCertificate" : "rds-ca-2019-root.pem"
... other config
}
the certificate can be obtained from here: https://s3.amazonaws.com/rds-downloads/rds-ca-2019-root.pem
The issue
Cannot even test if it is connecting because of the pem file processing exception.
Exception message: The certificate contents do not contain a PEM with a CERTIFICATE label, or the content is malformed.

Further technical details
Npgsql version: 6.0.6
PostgreSQL version: 13
Operating system: debian
This has also been posted in Github as an issue: https://github.com/npgsql/npgsql/issues/4675

I had a misunderstanding about the different SSL configuration that postgres has.
For this specific configuration
config = {
"SslMode": "Require",
"TrustServerCertificate" : true,
"SslCertificate" : "rds-ca-2019-root.pem"
... other config
}
You will need to use the SSL key, otherwise it won´t be possible to load and understand properly the pem file.
Because the escenario with the AWS cert is, basically, trust the root authority and use a cert, you will need to configure it as follows:
config = {
"SslMode": "VerifyCA",
// Delete this
// "TrustServerCertificate" : true,
"SslCertificate" : "rds-ca-2019-root.pem"
... other config
}
another thing that you have to do is include that pem file in you valid CA authorities.
Hope this help.

Getting the current user (aspnetcore identity)

I'm trying to get the id of the current user (the user executing the method) with Identity package. The context is a UserManager<ApplicationUser> (ApplicationUser is an IdentityUser).
var currentUserId = User.FindFirst(ClaimTypes.NameIdentifier).Value;
I add this to the list of claims when a user logs in. 'user' is the ApplicationUser from the DB.
new Claim(ClaimTypes.NameIdentifier, user.Id),
I also used this doc and added the following in Program.cs.
builder.Services.Configure<IdentityOptions>(options =>
options.ClaimsIdentity.UserIdClaimType = ClaimTypes.NameIdentifier);
However, I keep getting an "System.NullReferenceException: 'Object reference not set to an instance of an object.'" error.
The link also showed that I could get the current user as
var user = await userManager.GetUserAsync(User);
However, that just made the user null.
I'm using postman/swagger for debugging.
Here is the entire stack trace:
System.NullReferenceException: Object reference not set to an instance of an object.

Can someone tell me what I'm doing wrong?

I'm answering my own question.
I simply needed the [Authorize] attribute above the method.

How to catch and diagnose Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException?

This issue comes up in my server and I'm not able to catch where is it coming from, how can I track an issue like this and what might be the cause?
I have bugsnag setup in my server + newRelic and both don't give me information about this issue.
I'm running my application on a Ubuntu 18.04.5 using nginx.
Also is it normal that when this issue comes all the request on the server goes into Gateway timeout.

Check out this issue on GitHub: https://github.com/dotnet/aspnetcore/issues/23949. Especially this comment:
This exception seems to be thrown when a client aborts mid-request.
You can ignore this error by including the following MVC exception filter:
if (ex is Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException &&
ex.Message == "Unexpected end of request content.")
{
// "Unexpected end of request content."
// Microsoft.AspNetCore.Server.Kestrel.Core.CoreStrings.BadRequest_UnexpectedEndOfRequestContent
// ignore this
}

Why is the Export to PKSC12 for X509Certificate required in Windows (.Net 5) ? Possible side effect of X509.Export operation?

In a .NET 5 Asp.NetCore app (REST API) I need to call some public REST API requiring a client certificate.
Following code is not working on my local WindowsMachine (in docker container with Linux image (mcr.microsoft.com/dotnet/runtime:5.0-buster-slim) everything is fine) for loading the certificate:
...X509Certificate2.CreateFromPemFile(
this.certificateSource.PemFilePath,
this.certificateSource.PemKeyFilePath);
It always results in following exception:
System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.

Only when I am converting the certificate to Pkcs12 format via the Export method it works fine (under Windows on my local machine):
new X509Certificate2(X509Certificate2.CreateFromPemFile(
this.certificateSource.PemFilePath,
this.certificateSource.PemKeyFilePath).Export(X509ContentType.Pkcs12));
I tried to see the difference of the certificates (instances of X509Certificate2) but I could not figure them out. All properties and even the private fields are equal. I failed writing a Unit Test assuring the export of the Pkcs12 format because I don't know how to assert.
Has anyone an idea what the reason is for this difference between Linux and Windows and why I cannot see any difference in the instances at all. At the moment I am suspecting some side effect of the Export operation.

ASP.NET Core 3.1 MVC : Integer conversion between .net and oracle

I have an ASP.NET Core 3.1 MVC project, using Oracle.EntityFrameworkCore (tried all 3 latest version) to build code from an existing Oracle database.
EF Core provides the database first method to create models from the database tables.
In the Oracle database, the Book table has definition of
BOOK_ID NOT NULL NUMBER(10)
And EF Core created the field as int32
public int BookId { get; set; }
In the BooksController, GetBook method, there is this line:
var Book = await _context.Books.FindAsync(id);
When the id is small, for example, 5, it worked just fine. However when the id is big, for example, 412897, it will throw an error. The entire error stack trace by Postman is pasted below:

By searching online it seems to be the different definitions of integer by .net and Oracle. I found a solution to add HasConversion to OnModelCreating in DbContext class.
entity.Property(e => e.BookId)
.HasPrecision(10)
.ValueGeneratedNever()
.HasColumnName("Book_ID")
.HasConversion(t => Convert.ToInt32(t), t => Convert.ToInt32(t));
However it doesn't solve the problem. The error was as before.
Any suggestion is appreciated.
Thank you.
