dotnet user-jwts fails to parse tokens it creates

[enricoferrari]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

.net 8.0.403 Microsoft.IdentityModel.JsonWebTokens.JsonWebToken can not parse sub claims. (Even when the token is created by dotnet user-jwts)

To recreate:

1. Run: dotnet user-jwts create --claim "sub=test"
2. Run: dotnet user-jwts print {id-of-claim-from-step-1}

Result:
IDX12723: Unable to decode the payload '[PII of type 'System.String' is hidden. For more details, see https://aka.ms/IdentityModel/PII.]' as Base64Url encoded string.

Expected Behavior

dotnet user-jwts print is able to parse the token and print details to the console

Steps To Reproduce

To recreate:

1. Run: dotnet user-jwts create --claim "sub=test"
2. Run: dotnet user-jwts print {id-of-claim-from-step-1}

Result:
IDX12723: Unable to decode the payload '[PII of type 'System.String' is hidden. For more details, see https://aka.ms/IdentityModel/PII.]' as Base64Url encoded string.

Exceptions (if any)

Debugging this further in a server when parsing this token you can see that the inner exception details are unable to pares the sub claim:

Microsoft.IdentityModel.Tokens.SecurityTokenMalformedException: IDX14100: JWT is not well formed, there are no dots (.). The token needs to be in JWS or JWE Compact Serialization Format. (JWS): 'EncodedHeader.EndcodedPayload.EncodedSignature'. (JWE): 'EncodedProtectedHeader.EncodedEncryptedKey.EncodedInitializationVector.EncodedCiphertext.EncodedAuthenticationTag'. ---> System.ArgumentException: IDX14101: Unable to decode the payload '[PII of type 'Microsoft.IdentityModel.Logging.SecurityArtifact' is hidden. For more details, see https://aka.ms/IdentityModel/PII.]' as Base64Url encoded string. ---> System.Text.Json.JsonException: IDX11020: The JSON value of type: 'StartArray', could not be converted to 'JsonTokenType.String or JsonTokenType.Number'.

This is likely caused by #52286.

If you search for "no dots" in closed issues you'll see various issues that trace back to it.

Adding Microsoft.IdentityModel.JsonWebTokens and Microsoft.IdentityModel.Tokens to the project did not help.
