Closes #93
In Metabase we decided to clean up error handling based on values, as opposed to a mix semantically meaningful
nil
, magic keywords, and thrown exceptions.With this change we turn (expected) exceptions into error maps. We also wrap the
tables
in a map, to avoid an awkward untagged union with the error maps.Metabase has been made agnostic to these API changes, so upgrading will be easy.
