Juan Antonio Osorio Robles 35e49d5cdd Specify what to do if endpoint map environment don't match
this attempts to make the error message more useful. This error message
happens if the environment files containing endpoint map overrides
haven't been updated to match the base endpoint map (or the defaults).
