is the error thing addressed?

[yaelleC]

@andresmgot Not not yet, I'm still looking into it. I have not found the cause yet, but was able to replicate. Seems like the logs editor and the ARG one are not handling errors the same way.

[andresmgot]

:+1: What I did for the other types was to catch the error here:

https://github.com/grafana/grafana/blob/7505cf418bcbb286ddc154be0c64fbf4f066584d/public/app/plugins/datasource/grafana-azure-monitor-datasource/variables.ts#L96-L98

Not sure if that applies to this case (I know Logs is currently not showing the error either)

The backport to v9.0.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new branch
git switch --create backport-53059-to-v9.0.x origin/v9.0.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x d0d6562f63bf9368dbef2a71d3233960a721b208
# Push it to GitHub
git push --set-upstream origin backport-53059-to-v9.0.x
git switch main
# Remove the local backport branch
git branch -D backport-53059-to-v9.0.x

Then, create a pull request where the base branch is v9.0.x and the compare/head branch is backport-53059-to-v9.0.x.

hey @yaelleC I believe we should change the milestone here to 9.1.1 (and also the backport label)
