Fido2 Serialization is not working in FastEndpoint

[HakooDesai]

In Middle I've registered JsonStringEnumConverter(), as it is used by other endpoints,

app.UseFastEndpoints(c =>
     {
        
         // ref: https://fast-endpoints.com/docs/configuration-settings#specify-json-serializer-options

         c.Serializer.Options.PropertyNamingPolicy = JsonNamingPolicy.CamelCase;
         c.Serializer.Options.Converters.Add(new JsonStringEnumConverter()); // Serialize enums as strings in api responses (e.g. Role)

Now Attestation Registration Endpoint is not obeying to EnumMember, If I comment out
c.Serializer.Options.Converters.Add(new JsonStringEnumConverter());, it works. Can you please provide guidance on this one?

Thanks,
Hakoo.

Sorry - This is the first time I've heard about FastEndpoints.

Oh Okay... I've added/registered all FidoEnumConverters and Base64UrlConverter before these 2 converters and seemed like it's working. If that's a case, am I missing anything?
