Error: The terraform-provider-kubernetes_v2.19.0_x5 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.

Steps to Reproduce

  1. terraform apply

Expected Behavior

No Terraform panic

Actual Behavior

Terraform panic

Community Note

slavayssiere-stacklabs commented 1 year ago

It was an crash due to a image_pull_secrets.name with empty string. Solve using : 

dynamic "image_pull_secrets" {
  for_each = toset(length(var.image_pull_secrets) == 0 ? [] : [var.image_pull_secrets])
    content {
      name = image_pull_secrets.key
    } 
}
