[Bug]: Terraform resource `aws_codecommit_repository` argument `default_branch` is not adding default branch as expected

[reshma-ayyappan]

Terraform Core Version

0.14.5

AWS Provider Version

~> 4.0

Affected Resource(s)

aws_codecommit_repository

Expected Behavior

As per the documentation https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/codecommit_repository#attributes-reference , assume the optional parameter default_branch will add a branch to the repository

Actual Behavior

No default branch is not being added to repository as expected

Relevant Error/Panic Output Snippet

# aws_codecommit_repository.codecommit_repo will be created
  + resource "aws_codecommit_repository" "codecommit_repo" {
      + arn             = (known after apply)
      + clone_url_http  = (known after apply)
      + clone_url_ssh   = (known after apply)
      + default_branch  = "master"
      + description     = "This is the Sample App Repository, created from morpheus"
      + id              = (known after apply)
      + repository_id   = (known after apply)
      + repository_name = "sample-repo"
      + tags_all        = (known after apply)
    }

Plan: 1 to add, 0 to change, 0 to destroy.

  }
}

# Configure the AWS Provider
provider "aws" {
  region = var.aws_region
  access_key = var.access_key
  secret_key = var.secret_key
}

resource "aws_codecommit_repository" "codecommit_repo" {
  repository_name = "sample-repo"
  description     = "This is the Sample App Repository, created from morpheus"
  default_branch = "master"
}

The default branch property of the repository is set correctly in CodeCommit but it is not registered in terraform.tfstate as when you "terraform apply" a second time, it shows a change on the default_branch property. Say "yes" on the second apply, and it is set correctly.
