Can't see any debug

[itJunky]

Want to fix plugin for hiding memberlist https://github.com/haliphax/flaskbb-plugin-private-memberlist.
Trying to begin with output some debug by adding any logger or print into __init__,py of plugin:

    @app.before_request
    def check_logined_for_memberlist():
        'Check authentication before request is handled.'

        print(f'Текущий ендпоинт: {request.endpoint}')
        logging.config.dictConfig(app.config["LOG_DEFAULT_CONF"])
        # logging.basicConfig(filename='/tmp/LOG.log', encoding='utf-8')
        # logging.basicConfig(filename='LOG.log', encoding='utf-8', level=logging.DEBUG)
        logging.critical(f'Текущий ендпоинт: {request.endpoint}')

But nothing printed in logs dir and any other tried paths.
How can i see value of request.endpoint?

May be i need exception?

Wow shity magic (
Insert FLASK_ENV=development at run command and logger begins working correctly...

[itJunky]

But i see only logging message inserted into app.py after:

    @app.before_request
    def update_lastseen():

And see 0 message when insert same logging string into plugin __init__.py
How i can debug plugins correctly?

What wrong with memberlist plugin? App restarted when i save file from plugin but nothing else.
When i insert code from plugin

def configure_before_handlers(app):
    """Configures the before request handlers."""

    endpoints = (
        'forum.memberlist',
        'forum.search',
        'user.profile',
        'user.view_all_topics',
        'user.view_all_posts',
    )

    @app.before_request
    def update_lastseen():
        """Updates `lastseen` before every reguest if the user is
        authenticated."""
        logging.critical(f'Текущий ендпоинт в @app.before_request: {request.endpoint}')
        if current_user.is_authenticated:
            current_user.lastseen = time_utcnow()
            db.session.add(current_user)
            db.session.commit()

        if (request.endpoint in endpoints
                and not current_user.is_authenticated):
            return app.login_manager.unauthorized()

into app.py it is work correctly and redirects to login form when i click to memberlist link. But this is not plugin.

How can i use plugin https://github.com/haliphax/flaskbb-plugin-private-memberlist correctly?
