Error: The terraform-provider-k8s_v0.9.1 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

make: *** [plan] Error 1

Steps to reproduce the issue:
Set k8s provider in terraform:

terraform {
  required_version = "= 0.15.0"
  required_providers {
    k8s = {
      version = ">= 0.8.0"
      source  = "banzaicloud/k8s"
    }
  }
}

And tried to deploy manifest k8s resource

Expected behavior
Should apply manifest resource with no error

Having the same issue.

Currently it looks like the issue occurs from this line
https://github.com/banzaicloud/terraform-provider-k8s/blob/master/k8s/provider.go#L290

Not sure why, though

hi there,
I am getting same error when i changed direct kubernetes endpoint cluster IP to load balance endpoint cluster ip.
LB endpoint ip is reaching to k8s master node. But plugin still crashes.

I have the same issue.
I'm getting this after I deleted kubeconfig
When I ran command aws eks --region us-west-1 update-kubeconfig --name clustername
and run again, issue resolved.
But in my case I need to run any providers without any kubeconfigs
with similar construction:
provider "k8s" {
host = aws_eks_cluster.example.endpoint
cluster_ca_certificate = base64decode(aws_eks_cluster.example.certificate_authority.0.data)
exec {
api_version = "client.authentication.k8s.io/v1alpha1"
args = ["eks", "get-token", "--cluster-name", aws_eks_cluster.example.name]
command = "aws"
}
}

Having the same issue, rolling back to version: 0.8.2 fixed the problem for me.

Provider config:

provider "k8s" {
  host                   = var.cluster_endpoint
  cluster_ca_certificate = base64decode(var.cluster_certificate_authority_data)
  exec {
    api_version = "client.authentication.k8s.io/v1alpha1"
    args        = ["eks", "get-token", "--cluster-name", var.cluster_name]
    command     = "aws"
  }
}

Another "fix" was running this command: aws eks --region us-west-1 update-kubeconfig --name clustername as mentioned by @LevinDmytro2
