I'm facing the same issue. I've followed also the authentik documentation about RocketChat Oauth integration, and I'm getting the same error :

{
   "line":"70",
   "file":"oauth_server.js",
   "message":"Unable to base64 decode state from OAuth query: undefined",
   "time":{
      "$date":1721302560678
   },
   "level":"warn"
}

How can this be solved ?

@JackPala did you manage to make it work ?

This will happen when you have Merge Users enabled and you have an existing user that already exists matching your email and is disabled in Rocket.Chat. I had a test user created with my email and it caused this behavior.
