When running pgAdmin4 python wheel version on Ubuntu 18.04 & python 3.6, I met this bug when entering 127.0.0.1:5050 in my browser: ``` 2020-02-16 23:21:38,883: ERROR pgadmin: 'Request' object has no attribute 'is_xhr' Traceback (most recent call last): File "/usr/local/lib/python3.6/dist-packages/flask/app.py", line 1949, in full_dispatch_request rv = self.dispatch_request() File "/usr/local/lib/python3.6/dist-packages/flask/app.py", line 1935, in dispatch_request return self.view_functions[rule.endpoint](**req.view_args) File "/usr/local/lib/python3.6/dist-packages/flask_login/utils.py", line 260, in decorated_view return current_app.login_manager.unauthorized() File "/usr/local/lib/python3.6/dist-packages/flask_login/login_manager.py", line 152, in unauthorized return self.unauthorized_callback() File "/usr/local/lib/python3.6/dist-packages/pgadmin4/pgadmin/utils/session.py", line 355, in pga_unauthorised if not lm.login_view or request.is_xhr: File "/usr/local/lib/python3.6/dist-packages/werkzeug/local.py", line 347, in __getattr__ return getattr(self._get_current_object(), name) AttributeError: 'Request' object has no attribute ‘is_xhr' ``` I don’t know how to solve this problem, so I ask for help there. My dependencies are: Flask (1.1.1) Flask-BabelEx (0.9.4) Flask-Compress (1.4.0) Flask-Gravatar (0.5.0) Flask-Login (0.4.1) Flask-Mail (0.9.1) Flask-Migrate (2.4.0) Flask-Paranoid (0.2.0) Flask-Principal (0.4.0) Flask-Security (3.0.0) Flask-SQLAlchemy (2.3.2) Flask-WTF (0.14.3) Werkzeug (1.0.0) pgAdmin4(4.18)
