Important Factoids

This error happened when trying to look up a launch template, which was automatically created for an EKS node group.

In the aws_launch_template data source:

https://github.com/terraform-providers/terraform-provider-aws/blob/89791ba6931863e6d308df5af76b15d95f724a85/aws/data_source_aws_launch_template.go#L222-L225

in the corresponding resource:

https://github.com/terraform-providers/terraform-provider-aws/blob/89791ba6931863e6d308df5af76b15d95f724a85/aws/resource_aws_launch_template.go#L377-L382

with

The same unmarshaller getNetworkInterfaces is used.

Is there a workaround for this ? I actually need to update the launch template created by EKS Node Group

[jalaziz]

I'm seeing this error for non-EKS launch templates that were actually created by Terraform.

What's worse is that the launch templates have a value set for associate_public_ip_addresson the defined network interface.

The fix for this has been merged and will release with version 2.59.0 of the Terraform AWS Provider, likely tomorrow. Thanks to @jalaziz for the implementation. 👍
