Thanks for the contribution @kunxl-gg! Please make sure the email you've configured git with is linked to your github account (see Setting your commit email address) for more details, and sign the CLA 👍🏻

Note - we're cutting a new release next week so if you get this done before Wednesday it'll go into 10.1 :)

I have signed the CLA and configured my email on git. What next. This is a new laptop, probably that is why I didn't have my email configured.

Hmm @kunxl-gg, it looks like you'll need to re-commit with the new author details with the proper email address. The problem is with how the commit isn't linked to your user, which can be see by the commit missing your profile photo.

git commit --amend --reset-author --no-edit should do the trick. Note, this will rewrite the commit, so you'll need to git push --force that commit after.

Once the commit is attributed to your git user correctly, revisit the CLA link to trigger the check again. Then in in the week we will review + merge if all good 👍🏻

[kunxl-gg]

Done. Sorry for taking your time. Will take care of these minor details next time.

Tested this in both Storybook and in Dashboard import and it works great! Thanks for the contribution @kunxl-gg.

This should go out in the Grafana 10.1 release in the coming weeks 🥳
