Decodering payload returns AlgorithmNotExists but payload is decoded

[slimshader]

Hi,

I am trying to decode access token line this:

var decoder = new JwtDecoder();
var result = decoder.TryDecode(tokens.access_token, out AccessTokenPayload payload);

but result is AlgorithmNotExists even tho payload is correctly decoded, this makes impossible to continue with if (result == Success). Is that a bug on my part or library?
