Error 500 'NoneType' object is not subscriptable

[zorun]

Hi,

Thanks for this simple monitoring app :)

With a very simple BBB instance (no Moodle integration) I get 500 errors that seem related to #1

ERROR in app: Exception on /api/meetings [GET]
Traceback (most recent call last):
  File "/home/bbbmon/venv3/lib/python3.7/site-packages/flask/app.py", line 2446, in wsgi_app

    origin_server = meeting['metadata']['bbb-origin-server-name']
TypeError: 'NoneType' object is not subscriptable

and the second one once I "fixed" the first one:

ERROR:server:Exception on /api/meetings [GET]

TypeError: 'NoneType' object is not subscriptable

It seems that meeting['metadata'] is None in my case. As a hack I set it to an empty dict instead and the 500 errors went away.

Thanks for the explanation and thorough bug report. I'll make a fix tomorrow / sunday at the latest.
