Keats
can't handle null values if they are present
Json deserializing breaks when "aud" is null like in this case.
Here's the error message
Error(Json(Error("duplicate field `aud`", line: 1, column: 257)))
There is no other aud field.
I'm not sure why this error happens but that would be an invalid JWT either way. We should have a better error though but it looks like it comes from serde somehow

@Keats you are correct. It would be an invalid JWT. I didn’t realize that at first.
Our Ruby On Rails monolith issues these JWTs with a Devise plugin. We’re building a Rust microservice and I couldn’t get authentication to work. I realize now that it’s an issue with our Rails service. I just couldn’t figure out the issue because Rails and jwt.io would be able to validate it and Rust couldn’t.
