Is there a way to get some more informations for entries like this?
[2016-08-25 05:48:42.399 +00:00] [UtilsFilterPlugin] [InvalidPropertyParameter] 'JSON filter: GetPropertyValue': Parameters for property 'com.scur.engine.jsonfilter.getbyname' are invalid, reason: 'first parameter should be a map'
I don't think there is a way to make the error message more helpful... at least without touching the code. The message is shown when a property is called which expects JSON as parameter (for example a user-defined property of type JSON), but the parameter is not JSON but a string. I had a couple of problems with that error message in an environment where we fetched group information info a JSON objects, the error message was thrown whenever I tried to lookup a group from my JSON property, but the property was empty because no user groups were retrieved.
Unfortunately I have no more help to offer at this stage.
