Running under apache mod_wsgi. NoneType has no attribute 'put'

[blurks]

I'd like to run the youtube_dl_webgui under apache mod_wsgi, but i did not get it to work yet.
I am also quite new to flask an wsgi, so it might be my fault.

I allready tried to create a wsgi-script as described in the flask documentation:
from youtube_dl_webui.server import app as application

Apache loads that file without problems and displays the front page as it should, but any other actions result in an internal server error. Here is an example of an apache error log entry:

ERROR in app: Exception on /task/list [GET]
Traceback (most recent call last):

MSG.put('list', payload)
AttributeError: 'NoneType' object has no attribute 'put'

I think the problem is MSG = None at the beginning of server.py. The MSG Variable is only initialized, when you have an Instance of the Server class and call it's run method. And I don't do that, when I load the app as described above. So i guess i should somehow make an instance of that Server class in my wsgi-script. But then i don't know with which values I should initialize it (espacialy what is msg_cli).

So what would be helpful to me is either a note on how to supply this app using apache (or any other wsgi production server), or a fix for server.py (if that is possible) or even a complete wsgi script one could use.

What do you think about that?
