Hi folks,
I get an error popup " An error has occurred while handling the request. "
I try to narrow down the error root cause. To that end, I reviewed the error in the modeler
- Log Type: Error
- Log node: Connector
- Message: An error has occurred while handling the request. [User 'MxAdmin' with session id 'sdf' and roles 'Administrator']
- Stack trace:
--------
java.lang.IllegalArgumentException: requirement failed: mxObject should not be null.

I need some help analysing this.
I would say that "java.lang.IllegalArgumentException: requirement failed: mxObject should not be null." means, that a microflow expects an Object, while in some situation, the object is empty (which should not happen).
Any other suggestions what could have gone wrong?
Is there a way to get the information of the buggy microflow?
