OpenVidu Exception joining a room from android java

I am trying android sample project
but when joining a room the app is getting exeption from server
I can’t figure out what the problem is
There isn’t any problem in openvidu call app opening a room, but in android something is wrong
Please help
The following is the exeption on the server side:

A similar question has already been asked at Unable to join session. Session cannot be found. Code: 202. Check it out. You might get your answer.

This was fixed a few days ago for release 2.22.0.
If you follow instructions at openvidu-android - OpenVidu Docs, it should work fine.
