git-sync: "uid too long" when git-sync a dashboard with a long metadata.name

What happened?

using git-sync to import dashboards in the grafana v2 format leads to error




What did you expect to happen?

I expect the dashboard to be valie, according to docs at

Nothing says the metadata.name will be transformed into the legacy uid, which seems to be limited to 40 chars.

At least, I would expect the git-sync process to hash to metadata.name intp a UID instead of using the plain value, which, by Kubernetes design (as it seems you aligned on that) is 256 chars.

Did this work before?

don't know, git-sync and v2 API is pretty new

How do we reproduce it?

1. create a v2 dashboard with a really long name
2. import the dashboard using git-sync
3. experiencer the error and no dashboard


Is the bug inside a dashboard panel?

no
