bug version 1.40

[Elihai]

issuse:
aws_rds_cluster.default: Failed to modify RDS Cluster (demo): InvalidParameterCombination: The specified new engine version is same as current version: 9.6.9
status code: 400, request id: 04f08c7a-3aee-4754-96f1-b1e33bcacbe6

it happened when I trying to restore the last snapshot and the snapshot already configured to with rds engine version 9.6.9 it also happens when I trying to upgrade to 10.4.

so, for now, I back to version 1.39

Same problem here ! Had to switch back to 1.39 to make it work.

Ran into this myself tonight.

TF v0.11.10
AWS v1.41
Aurora RDS PostrgreSQL v10.4

Error

* aws_rds_cluster.postgresql: 1 error(s) occurred:

* aws_rds_cluster.postgresql: Failed to modify RDS Cluster (test-postgresql-cluster): InvalidParameterCombination: The specified new engine version is same as current version: 10.4
	status code: 400, request id: 565a<...>8b9fe5

Edit
Confirmed, forcing AWS provider to v1.39 got this working.

changing my provider to:

provider "aws" {
  region = "us-east-1"
  version = "~> 1.39.0"
}

fixed this, as it did for others. I was also trying to create an rds aurora postgresql 10.4 cluster from snapshot with latest aws provider and latest tf.

I was able to reproduce this with some new acceptance testing -- working on a fix now. 👍

Sorry for the trouble, folks! The fix for this has been merged and will release with version 1.43.1 of the AWS provider, likely later today. 👍

[DI-DaveGoodine]

Thank you sir!

[bflad]

This has been released in version 1.43.1 of the AWS provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.
