Grafana Image Renderer not working after update to 4.3.0

Add-ons Other

Hello,

Great work on the update! Everything seems te work fine after the update within OH itself.

Unfortunatly Grafana image rendering on my Pi4 doesn’t work anymore.
I can see the chromium-browse running and after a very long wait I get a 504 time-out.
At that point the process still seems to be running.

Any ideas what could have been changed in the update that could be the cause?

I get a long error message in grafana, but doen’t give me any clue where te look.

The message starts with:
level=error msg="Request error" error="Context.HTML - Error rendering template: error. You may need to build frontend assets \n template: error:16:42: executing \"error\" at <.Assets.Dark>: can't evaluate field Assets in type struct { Title string; AppTitle string; AppSubUrl string; ThemeType string; ErrorMsg error }" stack="github.com/grafana/grafana/pkg/web/context.go:112 (0x1902123)\ngithub.com/grafana/grafana/pkg/services/contexthandler/model/model.go:59

Regards,
Edwin

There really isn’t anything that would have changed in OH that would cause an error in Grapfana render. In OH 4.3 it’s going to make the same HTTP calls to the same ports in the same ways to Grafana as it always has.

I suspect that while you were upgrading/updating the software to get the new OH you also got a new Grafana Image Render and they changed the API.

I am using grafana version 11.4.0 and openHab 4.3 with no issues.
