Airflow Error when enabling user registration "get_user

I am trying to enable user registration, by configuring the "webserver_config.py" file. I have set the AUTH_USER_REGISTRATION variable to True and I have restarted the "webserver" container. I also tried performing down to the services and again up to the services and the error continues. Once enabled the variable already mentioned in the "Login" panel the Register button is shown, but when accessing the "Register" it shows the following error.

Traceback (most recent call last):

AttributeError: 'AirflowSecurityManager' object has no attribute 'get_user_datamodel'

I should add that both the "airflow.cfg" and "webserver_config.py" file I have as volume so as not to lose the configuration.

Python version: 3.7.12

Airflow version: 2.2.3

The variable AUTH_USER_REGISTRATION = True must be enabled in the file "webserver_config.py", verify that the variable AUTH_TYPE has AUTH_DB as value and finally validate that AUTH_DB is imported.

This is an issue in Airflow 2.2.3, #20449. Should be fixed in Airflow 2.2.4.
