             Summary: Create new Expression Language method isJson to determine whether an attribute is JSON
                 Key: NIFI-10612
                 URL: https://issues.apache.org/jira/browse/NIFI-10612
             Project: Apache NiFi
          Issue Type: New Feature
          Components: Core Framework
            Reporter: Daniel Stieglitz
            Assignee: Daniel Stieglitz


Create a new Expression Language method isJson to determine whether attributes are JSON or not. The addition of this method provides a short circuit of failure before attempting a JsonPath which otherwise would result in flow files yielding in the case the attribute is not JSON as detailed in NIFI-10396
