Not sure what caused this, but we have a 404 error in the dashboard on startup of 3.6.0 from the quay latest iib / fast channel:

Required sources failed when trying to create the workspace: 404 Not Found Not Found The requested URL was not found on this server.

I then tried to open the quarkus sample and got:

The new Workspace couldn't be created from the Devfile in the git repository:
Cannot define default editor
If you continue it will be ignored and a regular workspace will be created. You will have a chance to fix the Devfile from the IDE once it is started.

This might be a subtask of CRW-4077
