Terraform Version

Terraform v0.12.7

• provider.aws v2.41.0

Affected Resource(s)

• aws_kms_key

Terraform Configuration Files

locals {
  bucket_name = "some-bucket"
}

resource aws_kms_key bucket {
  description             = "KMS key for ${local.bucket_name} bucket"
  deletion_window_in_days = 14
}

Expected Behavior

KMS key should have been fully created.

Actual Behavior

Terraform created the key but failed to list the tags, error:

Error: error listing tags for KMS Key (***): NotFoundException: Key 'arn:aws:kms:***:key/***' does not exist
	status code: 400, request id: ***

Steps to Reproduce

It appears to be a race condition as the same operation was applied to many different AWS accounts at the same time but only one failed this way.

Next plan shows tainted aws_kms_key resource and apply successfully finishes.

1. terraform apply

Important Factoids

[jValdron]

I'm hitting the same race condition once in a while, with similar Terraform code:

resource "aws_kms_key" "rds_encryption" {
  description             = "Encrypts the source artifacts for RDS in an S3 bucket."
  deletion_window_in_days = 7
}

I believe the culprit is on this line: https://github.com/terraform-providers/terraform-provider-aws/blob/671177ac81c9ca9e4489b40616dd17a2c40b2794/aws/resource_aws_kms_key.go#L205

The keyvaluetags.KmsListTags call should probably have a retry, like every other calls in that method.

If that makes sense, I can try adding a retry to that call.
