AttributeError: x_arg

Worked fine with 4.0.5. After upgrading to 4.0.6 I am getting error as below. I don't see any migration notes or anything relevant in changelog or docs. What am I missing? Maybe it works with cli, but I was using it by importing from flask_migrate import upgrade in gunicorn startup hook and running it.

The fix is already on main, it will be released soon.
