User_agent is NoneType error

[DaneW]

I have recently started to get regular tickets for TypeError: argument of type 'NoneType' is not iterable on user_agent.is_mobile = 'Mobile' in http_user_agent

1. 2. 3. 4. 5. 6. 7. 8.

Traceback (most recent call last): File "/home/appgov/web2py/gluon/restricted.py", line 219, in restricted exec(ccode, environment) File "/home/appgov/web2py/applications/apg/views/default/index.html", line 62, in <module> File "/home/appgov/web2py/gluon/globals.py", line 340, in user_agent user_agent.is_mobile = 'Mobile' in http_user_agent TypeError: argument of type 'NoneType' is not iterable

Variables

user_agent.is_mobile	None
http_user_agent	None
user_agent	<Storage {'platform': <Storage {'version': None, 'name': None}>}>

I'm using 2.15.4 with Python 2.7 on PythonAnywhere.

Any suggestions?

Can you upgrade to the latest version, restart, and check if this still happens? If it does, please file an issue in github explaining how to reproduce.

Thanks. I have now upgraded to 2.16.1 but I'm afraid the problem is still there. The traceback is slightly different -

File "/home/appgov/web2py/gluon/globals.py", line 340, in user_agent

    user_agent = user_agent_parser.detect(http_user_agent)

TypeError: argument of type 'NoneType' is not iterable

The problem occurs when a user tries to access my home page (www.appgov.org) but other users get through successfully.

I will file the issue in GitHub.
