[Bug]: aws_iam_service_specific_credential password git credentials

[sergio1986bcn]

Terraform Core Version

1.9.5

AWS Provider Version

5.63.1,5.62.0

Affected Resource(s)

aws_iam_service_specific_credential

Expected Behavior

The password generated by the aws_iam_service_specific_credential resource should be valid and not contain unexpected special characters, such as the # character

The password should be directly usable for authentication to AWS CodeCommit, without the need to remove additional characters or make modifications.

Actual Behavior

Instead of generating a password that can be used directly without modification, the aws_iam_service_specific_credential resource is generating a password that includes a trailing # character and affects authentication to AWS CodeCommit.

Hey @sergio1986bcn 👋 Thank you for taking the time to raise this! I took a look at the resource schema, and it appears the resource is returning exactly what the API returns.

I noticed that you're using the -raw flag for terraform output. Is it possible that what you're seeing is a # being printed due to there not being a newline at the end of the returned string? For example, with the following configuration:

resource "random_pet" "test" {}

output "test" {
  value = random_pet.test.id
}

I have the following results:

$ terraform output
test = "upward-flounder"

$ terraform output -raw test
upward-flounder%

$ terraform output test
"upward-flounder"

$ terraform output -json test | jq -r '.'
upward-flounder
