Invalid user error when generating all certificates

[Hamza-Falih]

We encounter an error when we click on the "Generate all certificates" button :

This problem only appears on batch certificate generation whereas single certificate generation still works.

It appears that this problem is caused when an account has been deleted.

@dcadiou Have you encountered this error before ? Do you have any idea what might cause it ?

Thanks in advance !

Here are the results of my analysis:

I noticed that when I access the participants of the designated course, there are 81 participants.

Whereas when I check the learners registered for the attestoodle program, there are 135.

So there are learners in the attestoodle program who are not among the participants in the course.

I then noticed that there are learners whose accounts are suspended, others who are deleted and finally others who have two user accounts.

In particular : Three suspended accounts and three deleted accounts.

Two people with two accounts, one of which has been deleted.

When I compare it with our pre-production platform, on which we don't have this problem, there are the following differences : An account is not suspended and two other accounts are not deleted.

It seems to me that the problem comes from one of these last three.
