Hi Xtian,

Unfortunately, there’s not much information in this stack trace. The original Python exception has been converted into a Java PyException and the key information lost.

Do you have a rough idea when this is happening? e.g. is it when your active scanner check is running? Try surrounding the relevant parts of your code with Python try/except blocks, then do something like:


That stack trace should include more information which will help you diagnose the issue.

Please let us know if you need any further assistance.
