Many of the copied assignments had none as backend language id, but with a course-level override.
The course-level overrides data is missing after copying, and thus the migration to Programming Environments would not consider those when trying to obtain/create a matching programming environment (it replaced some of the commonly used images with their corresponding backen id).
To restore the lost bits (docker image override), update any of the assignments within the LDE CEL ChatGPT course that has none as backend id, to use the same environment as is obtained for the original assignments in the original courses. Origin information is also missing, but this can be restored by comparing assignment names and parent folder names.
