TypeError: can only concatenate str (not "NoneType") to str

Hy,
everytime i try to run the script I get the following error.

I'm on the development branch and the IP and port are correct.

ERROR:root:Something went wrong. Have you:
• Checked to make sure you're running the "development" branch of Stash, not "latest"?
• Checked that you can connect to Stash at the same IP and port listed in your configuration.py?
If you've check both of these, run the script again with the --debug flag. Then post the output of that in the Discord and hopefully someone can help.

logging.debug("Getting tag id for tag '"+name+"'.")

Any advice?
Thanks

Turns out my API-Key was wrong.

However the new output still has the same error, eventhough it seems to work
