Hello,
I have a recurring error happening on random stories, at random times, to random users (no specific patterns identidified but it happens pretty often).
Note that most of the times it’s only happening to one user at a time. It also come and goes.
The error is that the checklist cannot be load due to an eror (see screenshot bellow).

(It's in japanese, the error message says: " Cannot connect to Checklists. Please contact a developper.")
What has been tried already without results:
- Reloading the page / computer / different browser
- Log-out / Log-in again
- Editing the description of the description and reloading
- Editing the checklist from a user who is not experiencing the bug and reloading
I checked most of already existing threads about it and couldn'nt find a solution / answer.
This is causing great trouble to the development team, please help.
Thank you!
Best regards,
Andre
