Cannot get atproto OAuth to work with Deno

Trying to get to the bottom of the issue described here

Currently hitting the following issue:

JOSENotSupported: Unsupported key curve for this operation

  name: "JOSENotSupported"
}

Is this an issue with Deno compatibility or smth entirely different?
