What are you seeing

I have a working grafana_datasource to setup our latest Grafana server. As we are in the process of bootstrapping Grafana dashboards (as JSON files) to multiple Grafana installs, we need to enforce the datasource uid. However, when specifying the uid parameter, I get:

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: no parameter named 'uid'

What behaviour did you expect instead

The datasource uid should be enforced.
