Hi There

Have you configured MIDC(Method Invocation Data Collectors) on the application?

That exception is normally when you configure a MIDC, however not all transactions have that value set and it is null.

Ciao

Hi Ahmed

Best practice would be to configure a match condition in your MIDC to only collect the data when there is a value(non empty).

This would remove the exceptions

The second way, which I wouldn't recommend is just to add an exclusion to the error detection to ignore these exceptions
