InvalidOperationException when trying to do SignInAsync

[Lutando]

I am trying to sign a user in, in a normal controller. I have something along the lines of:

var claims = new List<Claim>
{
    new Claim(JwtClaimTypes.Subject, "xxx-xxx-xx-xxx),
    new Claim(JwtClaimTypes.PreferredUserName, "someusername"),
    new Claim(JwtClaimTypes.Email, "foo@bar"),
    new Claim(JwtClaimTypes.EmailVerified, "foo@bar:),
    new Claim(JwtClaimTypes.IdentityProvider, "idsvr"),
};

var ci = new ClaimsIdentity(claims, "password", JwtClaimTypes.PreferredUserName, JwtClaimTypes.Role);
var cp = new ClaimsPrincipal(ci);
await HttpContext.Authentication.SignInAsync("myscheme", cp);

And I get an exception saying InvalidOperationException: name claim is missing

In the constructor of the ClaimsIdentity I specified my name claim to be JwtClaimTypes.PreferredUsername (which is "preferred_username")

If I do add a name claim to my claims list, then sign in works fine with the above snippet. However we actually don't have name claims in our system. We want to use the "preferred_username" as the name claim in your abstractions.

InvalidOperationException: name claim is missing is not an exception thrown by the security stack.

It sounds like an IdSrv exception: https://github.com/IdentityServer/IdentityServer4/blob/dev/src/IdentityServer4/IdentityServerPrincipal.cs#L81

Thanks seems like it is, I could not find where this would be thrown. Thanks for the pointer.
