Describe the bug
So I know this is probably down to an issue with the override.yaml file, but i've literally formatted it exactly as per the documentation and used a proper code formatter to edit. Still, it does not boot when using the code in override.yaml

To Reproduce
Steps to reproduce the behavior, like:

Edit the override.yaml with the code below.
Reboot PiKVM
When attempting to access the webUI, I get error 500, Internal Server Error

Expected behavior
The webUI to load.
