This script will read your Overseer data and create/apply user tags to all of your sonarr/radarr instances

tag_sonarr_radarr_media_with_overseer_users.py

"""

This script will read your Overseer data and create/apply user tags to all of your sonarr/radarr instances, then create a filter in each connected -arr application for the users you specify. 
It is forward compatible with the future User Tagging feature of overseer, and formats the tag in the same 'id - lowercase username' pattern Overseer will
It only uses built in python libraries, so you should be able to download and run without much hassle.

NOTE:   YOU ARE REQUIRED TO USE IP:PORT CONNECTIONS FOR YOUR SONARR/RADARR INSTANCES INSIDE OF OVERSEERR
        This will NOT utilize docker-compose style hostnames at the moment, and I don't use them personally, so I don't see myself adding them

Steps to use:
1. Add your Overseer API key
2. Add your Overseer Internal URL (might work with external domain url, but I didn't test)
2.5 Edit the Default values for number of users/requests
3. Press Play and wait

I'm late to the party, I know, but I'm getting an index out of range error similar to others.

Is there something that I can modify to have that list index work as intended?

For anyone who comes after me:
The key thing to modify is in Overseerr -> Services -> Radarr/Sonarr -> external URL in that specific popup. That was the bit I was hung up on.

NGL, chatgpt helped by adding in this error handling.
