Expected Behavior

Terraform command displays planned changed.

Actual Behavior

Terraform crashes before prompting to apply.

Steps to Reproduce

Configuration private.

I think possibly it was related to the new addition of Cognito support in the aws_lb_listener resource.
I created a listener action of type "authenticate-cognito" in Terraform and then removed it manually.

Can confirm that manually recreating the cognito listener action allows Terraform to run without error again.

@brett-richardson Can you reliably reproduce this? The error looks like it's just your connection is dying when Terraform is talking to the AWS API.

If you can it would be useful if you could provide a minimally verifiable example that does regularly reproduce this error.

Bug fix pull request submitted: #6319

[bflad]

The fix for actions deleted outside Terraform has been merged and will release with version 1.43.0 of the AWS provider, likely middle of next week. 👍

[bflad]

This has been released in version 1.43.0 of the AWS provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.
