Hi Karen,
I am able to confirm that the groups and the sections associated with the course are still there with the users, so I am not sure what else could lead to this error.
Any other angle to look?
Thank you for your prompt assistance.

Hi Narasi,
>From the code, it looks like something related to the groups/sections in that site. Does this assessment release to groups/sections? If yes, can you check if these groups/sections are still valid? Or have them been removed and recreated?
Thanks,
Karen

Thanks Karen. We are using the 2.9.x version of Samigo from revision 113710.  It's been modded for calculated questions per our developers that part did not touch the AuthorActionListener.java code.


Thanks,
Narasi

Hi Everyone,

We are seeing this issue wherein when anyone with  instructor type role access Samigo an error report is thrown out error report posted below.

On looking at the course backup I am seeing 4 of her exams does not have an author - would that cause this error? If it possible to insert an author into an exam if the field is blank and thereby fix this issue? Any recommendation to overcome this issue will be greatly appreciated.

Thanks,
Narasi
