Testing

Just build the image and test it. It should be working fine on any installation.

Documentation

Does not apply

[baldarn]

I confirm it solves the issue

For others coming here that hadn't merged a non merged branch before (not even sure that's the right terminology), this command fixed it for me.
I had to install gh first and authenticate my account - not sure if you can do it with github fetch and merge or something.
'gh pr checkout 101'
then
'docker compose up' as per instructions

[marshalleq]

Four months, perhaps we can merge this now?

[victormark97]

This fixes the problem, can be merged! It's been a year almost 😆

[marshalleq]

Does this mean it's getting merged, or is it just another bump? I need to reinstall so could wait until it's done so that it can be tested.
