Missing Claims via JWT Web Token - jwt

Question

I have the following code that creates a JWT token in a webapi core application.
var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_config["Jwt:Key"]));
var credentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256);
var claims = new[] {
new Claim(JwtRegisteredClaimNames.Sub, userInfo.Username!=null?userInfo.Username:string.Empty),
new Claim(JwtRegisteredClaimNames.Email, userInfo.Email!=null?userInfo.Email:string.Empty),
new Claim(JwtRegisteredClaimNames.Jti, userInfo.AccountId!=null?userInfo.AccountId.ToString():Guid.Empty.ToString()),
new Claim(JwtRegisteredClaimNames.NameId, userInfo.UserId!=null?userInfo.UserId.ToString():Guid.Empty.ToString()),
new Claim(JwtRegisteredClaimNames.UniqueName, userInfo.ClientId!=null?userInfo.ClientId.ToString():Guid.Empty.ToString())
};
var token = new JwtSecurityToken(_config["Jwt:Issuer"],
_config["Jwt:Issuer"],
claims,
null,
expires: DateTime.Now.AddMinutes(20),
signingCredentials: credentials);
return new JwtSecurityTokenHandler().WriteToken(token);
However when I try to get the claims back after the client has called a webapi end point, I only have the following claims. As you can see the "JTI" claim is fine, but the "UniqueName" claim is missing.
[0]: {http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier: }
[1]: {http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress: }
[2]: {jti: f7c5af77-d0c4-4026-9b33-2fe9fbf5ee28}
[3]: {http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier: 00000000-0000-0000-0000-000000000000}
[4]: {http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name: b34a1b42-df24-42a3-93d7-68e88523602f}
[5]: {exp: 1581973428}
[6]: {iss: Test.com}
[7]: {aud: Test.com}
What do I need to do to get the claim to appear?
Just to note that the claim that I set as JwtRegisteredClaimNames.UniqueName does appear in the claims but not under that name. Its value is set under the item
[4]: {http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name: b34a1b42-df24-42a3-93d7-68e88523602f}
However this is not brought back when use the following as it is null
identity.FindFirst(JwtRegisteredClaimNames.UniqueName).Value;

Answer 1

However this is not brought back when use the following as it is null
identity.FindFirst(JwtRegisteredClaimNames.UniqueName).Value;
To fix the above issue, you can try to clear the inbound claim type map using following code snippet in Startup.cs
System.IdentityModel.Tokens.Jwt.JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();
Test Result
Set testing value for JwtRegisteredClaimNames.UniqueName
//just for testing purpose
new Claim(JwtRegisteredClaimNames.UniqueName, "b34a1b42-df24-42a3-93d7-68e88523602f")
Can get expected value using identity.FindFirst(JwtRegisteredClaimNames.UniqueName).Value
