Steps to Reproduce

1. terraform apply when creating new clusters

Expected Behavior

Apply succeeded.

Actual Behavior

│ Error: Value Conversion Error
│ 
│   with module.eks_cluster.provider["registry.terraform.io/hashicorp/kubernetes"],
│   on .terraform/modules/eks_cluster/auth.tf line 96, in provider "kubernetes":
│   96: provider "kubernetes" {
│ 
│ An unexpected error was encountered trying to build a value. This is always
│ an error in the provider. Please report the following to the provider
│ developer:
│ 
│ Received unknown value, however the target type cannot handle unknown
│ values. Use the corresponding `types` package type or a custom type that
│ handles unknown values.
│ 
│ Path: exec
│ Target Type: []struct { APIVersion basetypes.StringValue
│ "tfsdk:\"api_version\""; Command basetypes.StringValue "tfsdk:\"command\"";
│ Env map[string]basetypes.StringValue "tfsdk:\"env\""; Args
│ []basetypes.StringValue "tfsdk:\"args\"" }
│ Suggested Type: basetypes.ListValue
╵}

Important Factoids

A workaround is to pin the Kubernetes provider to 2.24.0.

I got the same error in the latest release v2.29.0

Thank you for documenting that 2.24.0 works as that unblocked us.

There were a lot of changes between v2.24.0...v2.25.0
