• Plugin E2E
• Plugin Meta Extractor

Problem

plugin-e2e provides a declarative way to create new users in a setup project. Under the hood, plugin-e2e uses the Grafana api to do this, however it's using basic auth which is disabled by default in scaffolded plugins.

Solution

Any interaction with the Grafana http api should be done on behalf of a logged in user.
