Had to revert to 3.10.1 as 3.11.0 gives the above error regardless of the project/data.

This code has been introduced in 3.10.0 so before the version you are releasing.

Reading the changelog between 3.10.1 and 3.11.0, I don't see anything.

I suspect your were using Lizmap with a missing "signal" when it's fetching the metadata from your server.

I guess you can upgrade again and just try to check your server list, does all server as a QGIS server version ?

[gioman]

@Gustry seems you are right.

[Gustry]

Thanks for the feedback.

There is still an issue somewhere, you shouldn't have a Python error displayed. So there is somewhere I should add some safe-guard. Your server must has been "ready" (with metadata fetched) before pressing OK button from Lizmap. It's a matter of a few ms or second I guess. I will think about that.

Slightly improved in the coming latest bugfix 3.11.1
