-------------------------------------------

             Summary: Return clearer JSON validation errors to clients (instead 
of HTTP 500)
                 Key: FINERACT-1124
                 URL: https://issues.apache.org/jira/browse/FINERACT-1124
             Project: Apache Fineract
          Issue Type: Bug
            Reporter: Michael Vorburger


See FINERACT-932 for general background; on 06.08.20 (only) there were x2 of 
these in logs of [https://www.fineract.dev|https://www.fineract.dev/], which 
made me think that, in an ideal world, we could catch this and have 
integrationt tests ensuring that we return clearer JSON validation errors to 
clients instead of HTTP 500 internal server errors, e.g. in cases like this:

{noformat} java.lang.IllegalStateException: Not a JSON Array: "Brasil"
