Research direction
Start in compiler/src/Generate/JavaScript.hs around line 198 and reproduce the error with an elm.json that does not contain lamdera/codecs. Trace the assumption about elm/json and determine the expected behavior for that case. Done means compilation no longer raises the Map.! error when lamdera/codecs is absent.
