grafana_dashboard resource creation intermittently fails with 422 error

Terraform Version

Terraform v1.1.7

• provider registry.terraform.io/grafana/grafana v1.23.0

Affected Resource(s)

• grafana_dashboard

Bug Description

I've noticed that trying to create multiple dashboards (~15 at the time) ends with 422 error for a couple of them They can be successfully retried without any modifications. It appears that for some reason provider sends empty POST request to grafana.

It's always reproducing for me on this amount:

Plan: 14 to add, 1 to change, 19 to destroy.

All dashboard resources have same configuration with overwrite = true

e.g. resource "grafana_dashboard" "some_dash_name" { config_json = file("../dashboards/k8s/some_dash_name.json") folder = grafana_folder.some_folder.id overwrite = true }
