@unguiculus @Whyeasy not sure what is wrong here, but when I try to sign the CLA, it says that the item does not exist..

Error

There is no CLA to sign for grafana/helm-charts

(could not find linked item for owner grafana and repo helm-charts)

@ludydoo Could you bump the Chart.yaml version to latest and sign DCO please? Currently it seems CLA signing is optional.
