Error on upgrading amplify GraphQL Transformer v1 to v2

I'm using the guidelines on https://docs.amplify.aws/cli/migration/transformer-migration/ to migrate an Amplify Project from v1 to v2, but when I try to do an "amplify push" after succesfully ran "amplify migrate api" I'm getting this error:

CREATE_FAILED AuthRolePolicy049E37F651 AWS::IAM::ManagedPolicy Thu Jan 13 2022 10:21:04 GMT-0300 (Argentina Standard Time) Cannot exceed quota for PoliciesPerRole: 20 (Service: AmazonIdentityManagement; Status Code: 409; Error Code: LimitExceeded; Request ID: 430bca73-5e2f-47a9-8f99-d1b1ed4e9483; Proxy: null)

Before the migration I didn't have any quota limitation issue, I don't know if it is related to the migration or if it's a limitation of the new transformer version.

What can I improve on my schema.graphql to reduce the value on "PoliciesPerRole"?

Thanks!
