Describe the issue

The issue is that when a user tries to log into their BattleNet account, it stops them and states "400 The state parameter must be provided". I tried just setting state="none" but when the request went thru, it threw an error about the "nonce".

How to reproduce

Create a bare bones next auth project with the BattleNet provider. Then attempt to sign in.

Expected behavior

Should instead of requesting the state parameter, allow the user to log into their account.
