Crash when no video file is present

[zerodayz1]

The script fails when encountering an entry in Emby where there is no video present. An odd case, I agree.
But if a show or movie is present in the Emby DB, but the corresponding video file is missing the following error is thrown:

Traceback (most recent call last):
  File "/opt/scripts/jellybean/run.py", line 176, in overlays
    episodes = response3.json()['Items']
  File "/usr/lib/python3/dist-packages/requests/models.py", line 900, in json
    return complexjson.loads(self.text, **kwargs)
  File "/home/seed/.local/lib/python3.10/site-packages/simplejson/__init__.py", line 514, in loads
    return _default_decoder.decode(s)
  File "/home/seed/.local/lib/python3.10/site-packages/simplejson/decoder.py", line 386, in decode
    obj, end = self.raw_decode(s)
  File "/home/seed/.local/lib/python3.10/site-packages/simplejson/decoder.py", line 416, in raw_decode
    return self.scan_once(s, idx=_w(s, idx).end())
simplejson.errors.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/opt/scripts/jellybean/run.py", line 538, in <module>
    main()
  File "/opt/scripts/jellybean/run.py", line 114, in main
    overlays(library, library_type, items, config_vars)
  File "/opt/scripts/jellybean/run.py", line 177, in overlays
    except (json.JSONDecodeError, requests.exceptions.JSONDecodeError, simplejson.errors.JSONDecodeError):
AttributeError: module 'requests.exceptions' has no attribute 'JSONDecodeError'

I'll clean up the entries from Emby, but would be good to allow continuing on errors like this, as there is no way to move past it, fails every time on missing files.
