Problem Description

Hello !

I'm trying to build a stack from a git repository, my credentials are ok (github app PAT token), but I'm ending up with 1 issue when I click the "Deploy the stack" button : Top-level object must be a mapping

Expected Behavior

Deploy the stack properly !

Actual Behavior

Here is what I found on docker logs of portainer :

Additional Information

I verified my compose.yaml file muuuultiple times, without success...

I don't know where it comes form because I tried to build a stack over https://github.com/docker/awesome-compose/blob/master/wordpress-mysql/compose.yaml and it works....
