Enable Automatic Certificate Generation is fail on Maple after Lilac upgrade

Hi,
I have a problem on automatic certificate generation issue on Maple after upgrading from Lilac (with Tutor installation method).

On my previous Lilac, I can enabled a course automatic certificate generation by set the early_no_info value (18.5. Ending a Course — Building and Running an Open edX Course documentation) and somehow this Certificates Display Behavior were disappear from Maple’s Course Advanced Settings.
Secondly I then enabled certificates.auto_certificate_generation waffle switch on Django Admin.

Now if a learner go to Progress page it couldn’t be opened and show “There was an error loading this course.” error. Check on LMS log shown:

I should disabled the certificates.auto_certificate_generation waffle switch flag to fix this and page will display normally. But, no certificate download link on this page when a learner has passed the exam.

I know there are some various bugs fixed and updates of Certificate on Maple version but since I’m new and have no more deep knowledge in this area.

I really appreciate if someone could assist me on this issue.
Thank you in advance.

This issue seems duplicate of this one

Now this is an ominous error. Is there anything interesting in the logs of other containers?

Hi @Zia_Fazal it’s solved!
By enabling persistent grades via Django admin.

But the link for Certificate download is still not appear.

Thank you so much!

@regis , I will check…
