I’m getting the following error occasionally when running a Prefect flow using Dask CloudProvider.

ClientException('An error occurred (ClientException) when calling the RegisterTaskDefinition operation: Too many concurrent attempts to create a new revision of the specified family.')

Hey @Andrew Hannigan, see this thread . This is a known issue for ECS.

Thanks @Kevin Kho - reading through it looks a solution is still pending. My takeaway is that the best thing to try now is to set the env variables:

- Name: AWS_RETRY_MODE
  Value: adaptive
- Name: AWS_MAX_ATTEMPTS
  Value: 100

Yes it is pending unfortunately.

Does that sound right to you?

Yep that sounds right to me!

Okay! Will give those env variables a try, thanks!
