Failing to update tags on the `AWS::RDS::DBClusterParameterGroup` resource


We are having an issue with CloudFormation for the past 2 days. This has worked flawlessly for over a year, with multiple daily deployments, but all of a sudden broke.

We are getting the following error during the CF deployment:

Resource handler returned message: "Exceeded attempts to wait" (RequestToken: d5d4641e-a1ca-ad53-5eb2-64ac9b8d9863, HandlerErrorCode: NotStabilized)

The following resource(s) failed to update: [DatabaseWarehouseParameterGroupXYZ].

This is happening on a tags update for the RDS Parameter Group (AWS::RDS::DBClusterParameterGroup). Which makes no sense as it is a simple operation. It is just updating one value for another (build ID).

  • There have been no related changes to our infra.
  • We have tried this many times both thru the pipeline and manual local deployments over the last 2 days.
  • The timeout happens after ~ 20 minutes, which should be more than enough to update the tags.

Hi @m0ltar! I was updating a typo error in my answer and maybe I accidentally clicked on Delete instead of Update.

Here is my original answer:

I just tried a simple CloudFormation template on my end with AWS::RDS::DBClusterParameterGroup resource and was able to update a Tag value successfully. By any chance, is your parameter group associated with any stopped DB cluster?

Glad this helped!

  • Thank you, joahna! You nailed it with the "stopped DB cluster" comment!


Good call, @joahna! Indeed, we had a stopped clone of a production instance that was sharing the parameter group. This was not obvious from the CF resource list, as the clone was not part of the stack. Thanks for the tip!

I don't know why, but @joahna's answer is not visible anymore after I refreshed the page.
