I'm trying to build and deploy an image on GCP with cloud build. I have a rails api repo on bitbucket running on docker, the repo is synced with google cloud repository

I configured a trigger on cloud build when a commit is made on my master branch.

Trigger Configuration:

Service account permissions:

But when the master branch gets a commit, the triggers returns the following error: our build failed to run: <br>Couldn't read commit xxxxxxxx

Build Error:

I tried checked the GCP doc and I can't find anything. I think the issue might be on the IAM level, maybe the service account needs more credentials.
