Ok guys, I just found the solution !!
As It’s logged nowhere the fail is coming from a library update 
In my case, it was the browser-tools that I had to update to the last version 1.4.0
And the other thing I had to do is put the checkout step first in the steps (don’t ask me why but it’s now required 
)
I hope it can help you to fix this bug !
If it’s not, my advice is to remove all your custom configurations until it compile successfully, then add it back step by step
