Amplify build fails with AssumeRole error

[JulioSarmiento]

I recently deployed AWS TEAM to a new account - delegated. The installation went well, however, the Amplify build keeps erroring out with the following: [ERROR]: !!! Unable to assume specified IAM Role. Please ensure the selected IAM Role has sufficient permissions and the Trust Relationship is configured correctly.

I have reviewed the role's permissions and no matter how I tweak it, it fails. Has anyone come across this issue? I am using us-west-2 and below is the Trust Relationship.
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "amplify.amazonaws.com" }, "Action": "sts:AssumeRole" } ] }

Thank you in advance.

This was apparently due to not being able to pull from Github. I reconnected the branch using AWS / Github app and the build is running fine now.
