Hey there @ianaya89 👋🏻, thanks for reporting the issue and sorry you're running into trouble here.

I'm going to close this issue as the error is coming from HCL (and it's underlying type system), so I believe the Terraform core issue tracker or HCL issue tracker would be a better place to discuss this behavior, as there is nothing terraform-plugin-framework can do about this error:

• https://github.com/hashicorp/terraform/issues
• https://github.com/hashicorp/hcl/issues

An additional note, in your example, node_groups is a set type, where each element is identified by the value itself, rather than an index like a list, so your expected behavior of printing a numerical index isn't something that HCL/Terraform could achieve.

@austinvalle Thanks for taking a look!
