CodeBuild Phases Failure

I setup a CI/CD pipeline (CodeCommit -> CodeBuild -> CodeDeploy) controlled by CodePipeline

Whether using environment variables or hardcoded values, I receive the same error. I made sure my service role has the below permissions:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "ecr:GetDownloadUrlForLayer",
        "ecr:BatchGetImage",
        "ecr:CompleteLayerUpload",
        "ecr:UploadLayerPart",
        "ecr:InitiateLayerUpload",
        "ecr:BatchCheckLayerAvailability",
        "ecr:PutImage"
      ],
      "Resource": "arn:aws:ecr:eu-west-1:<ACCOUNT_ID>:repository/<Respository_name>"
    }
  ]
}
