Should provisioned dashboards have datasource uids?

Grafana Configuration
,
8

I just had a similar issue. I tried the suggested methods, but I found another solution. In the grafana provisioning tutorial, I noticed the following two things:

# definition of the data sources:
datasources:
  - name: TestData
    type: testdata

Then in the json, they suggest to refer to the name by string, not an object containing type and UID:

 "panels": [
    {
      ...
      "datasource": "TestData",
      ...

I hope that helps.
