[ERROR] Trying to run scenario or save returns UDT (User defined type) not found

Hi Guys

I am trying to run a scenario but I am getting “UDT (User defined type) not found: UDT not found ‘json:149722’.” I also get the same message when trying to save. It is not indicated as to which node is responsible. The error appears as soon as run in initiated so no logs are created.

Any help greatly appreciated.

Thank you.

Did you import any modules? You need to go to each module, especially JSON and aggregator modules, and click Save. This should resolve any missing data structures by clearing that field, since data structures cannot be imported.

Hope this helps! Let me know if there are any further questions or issues.
