You can use the Last errors or Last errors command to obtain the error sequence (i.e., the error "stack") at the origin of the interruption.
Btw: I was looking for the explanation of an error code and could not find it.
Looked in:
https://developer.4d.com/docs/20-R10/Concepts/error-handling
https://developer.4d.com/docs/20-R10/Debugging/basics
https://developer.4d.com/docs/20-R10/commands/last-errors
https://developer.4d.com/docs/20-R10/commands/on-err-call
Via Google I found the old documentation: https://doc.4d.com/4Dv19/4D/19.8/Error-Codes.200-7112030.en.html
