In one of the courses, an error occurs when trying to create a backup copy of the test: "Missing required parameter (id)".
The test was previously ported from moodle 1.9.9 to moodle version 3.11.6 and works great.
Why then it is not copied? What parameter is missing?
I turned on debug mode and error output, but I didn't see anything on the page. I looked in the logs, but found nothing there (little experience). I cleared all site caches through the Administration section.
