Grafana charts preview not working

[bunghi]

Since migration to IcingaDB and Grafana module v2 we are not able to see the charts preview anymore in Icingaweb. If i click on the "invisible" chart I'm redirected to Grafana where the chart is loaded correctly, just the preview is not working.

Expected Behavior

Before migration used to work and charts preview were shown

Current Behavior

Empty chart but timeframe selection is possible

I am facing the same issue. Might it have to do with the fact that we are both using PHP 8.2? The Requirements state PHP 8.1.

mine started working again after modifying 3 files according to https://github.com/dsh2dsh/freebsd-ports/commit/41ed29c6d86e6f51a40faa3f59d1be8a0a0b6a6f

I think this relates to https://github.com/Mikesch-mp/icingaweb2-module-grafana/issues/325
