I just tried to search for vehicle Enum fields and found that you seem only to be able to get a result if your search string matches exactly an Enum value, otherwise you get a 400 error.
E.g.:
query: { “engineType”: { _eq: “GASOLINE”}} → gives the expected result
query: { “engineType”: { _eq: “GAS”}} → 400 error; expected: empty result
query: { “engineType”: { _like: “%S%”}} → 400 error; expected: all vehicles with an engine type designation (Enum value) that contains ‘S’
Is that the intended behaviour or is this a bug?
