'Exception generated: cannot use a string pattern on a bytes-like object' when sending Plex notifications

[akang6]

Describe the bug
I use Sabnzbd and nzbToMedia to post process new episodes. I noticed that I was getting notifications that post processing failed and nzbToMedia was saying the post processing failed but when I checked I saw that it did complete. After some digging through the logs, I saw that there was an error at the end of post processing when Plex was being notified. Testing my Plex notifications in the settings seems to work fine, just during the post processing.

To Reproduce
Steps to reproduce the behavior:

1. Turn on Plex notifications
2. Post process a new episode
3. See error in log

Expected behavior
Plex to be notified and post processing to be completed cleanly

I have also been getting this identical exception for every show downloaded and sent to post-processing. Same modules in the traceback, same line numbers for the error.

It's because of the extra scripts you are using. Disable extra scripts or use Python 2.7 if you don't want to wait for the next release. Fixed with 6834891
