Hello ! I'm facing an issue when deployment my app (after upload and resetdb on otree hub) that i built on otree, i got an application error when deploying. And the following logs errors are mostly : 

"at=error code=H10 desc="App crashed" method=GET path="/robots.txt" host=efrei.herokuapp.com request_id=9582d9f3-c4de-43d1-8bc" ...

Any help would be very appreciated, thanks in advance.

i'm adding more logs (they're very long...) : 2023-05-03T10:12:20.611362+00:00 heroku[run.8951]: State changed from up to complete

The last message "app[heroku-postgres]: .............. sample#wal-percentage-used=0.06352662081219163" is repeating a lot by the way, before reaching once again a similar message error :
