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

cc'ing the contributors from 2.25.0: @arybolovlev @jrhouston @andremarianiello @BBBmau @wonko (sorry for the ping but this seems like a bad regression if you folks are unaware)

Seeing this in 2.33 as well.

Thanks to all for the information in this issue thread.

Our Kubernetes provider is pinned to 2.24.0 as described here to get around this for now.

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.76"
    }
    kubernetes = {
      source  = "hashicorp/kubernetes"
      version = "2.24.0"
    }
  }
}

Any updates are appreciated.
