Current Behavior

When we submit valid JSON data to the Datastore API but in a form that does not validate against the query schema, as expected we get a 400 error and some error output. However, submitting completely invalid JSON results in a 500 error.

This issue is specific to the "resource query" datastore endpoint. Submitting invalid JSON to the Metastore API, for instance, will return a 400 "Invalid JSON" response. The datastore should have the same behavior.

Expected Behavior

Submitting completely invalid JSON, such as

{
  "foo": bar,
}

should result in a 400 error and some output.
