Issue with AWS Lambda Alias and Provisioned Concurrency

This feeds off of question: Issue with Creating Application Auto Scaling with AWS Lambda using Terraform

I put a Lambda Alias in my terraform that I'm going to use in my Provisioned Concurrency Config. I get the following error during the aws_lambda_provisioned_concurrency_config resource creation:

Error: error getting Lambda Provisioned Concurrency Config (arn:aws:lambda:us-east-1:<AWS-ACCOUNT-#>:function:foo:PC): ValidationException: status code: 400, request id: 82c5e589-d455-4d53-abea-bac8e5b5a2ea

My terraform is below:

resource "aws_lambda_alias" "foo_pc" {
  name             = "PC"
  description      = "foo PC Alias"
  function_name    = aws_lambda_function.foo.arn
  function_version = aws_lambda_function.foo.version
}

resource "aws_lambda_provisioned_concurrency_config" "foo_provisioned_concurrency" {
  function_name                     = aws_lambda_alias.foo_pc.function_name
  provisioned_concurrent_executions = var.PCInit
  qualifier                         = aws_lambda_alias.foo_pc.name
}

I want the alias to point to the latest deployment of the lambda. Can I not use in my aws_lambda_function.foo.version in my lambda alias?

From the AWS docs, in case Lambda provisioned concurrency auto-scaling:

Lambda provisioned concurrency - The resource type is function and the unique identifier is the function name with a function version or alias name suffix that is not $LATEST. Example: function:my-function:prod or function:my-function:1.

In case of an alias, the resource id should look something like this:

resource_id = "function:${aws_lambda_function.foo.name}:${aws_lambda_alias.foo_pc.name}"

Update for the error message:

There is an open issue reported for the provider in GitHub: https://github.com/hashicorp/terraform-provider-aws/issues/12923
