Grafana: Demo/OpenTelemetry Collector fails to load

[zmccoy]

Bug Report

v1.0.0

Symptom

When navigating over to the Demo/OpenTelemetry Collector an error of Templating Failed to upgrade legacy queries Datasource ${DS_PROMETHEUS} was not found pops up in the top right. None of the graphs load. I could be missing something silly that I should have been doing as well, but I've reproduced this twice in a row locally.

What is the expected behavior?
Graphs would all load without error.

What is the actual behavior?

An error message of Templating Failed to upgrade legacy queries Datasource ${DS_PROMETHEUS} was not found is produced in the UI.

Reproduce

After starting up the docker compose go to: http://localhost:8080/grafana/d/BKf2sowmj/opentelemetry-collector?orgId=1&from=now-5m&to=now
