Error: The terraform-provider-kubernetes_v2.36.0_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

What should have happened? Terraform should apply the kubernetes_manifest resource successfully.

Actual Behavior

What actually happened? Terraform produces the error above.

Important Factoids

The crash only happens when we have more than 1 elements in workflows[] However, when removing the second workflow (- name: "test2"), the issue disappears:

resource "kubernetes_manifest" "testkube-manifest" {
  manifest = {
    apiVersion = "testworkflows.testkube.io/v1"
    kind       = "TestWorkflow"
    metadata = {
      name      = "test"
      namespace = "testkube"
    }
    spec = {
      steps = [
        {
          name = "some-steps"
          execute = {
            workflows = [
              { name = "test1" },
            ]
          }
        }
      ]
    }
  }
}

Also encountering this error when using "kubernetes_manifest" to create an argoproj.io/v1alpha1 ApplicationSet in EKS 1.32. Rolling the provider back to v2.29.0 fixed the issue, so it seems to have been introduced in v2.30.0.

resource "kubernetes_manifest" "applicationset" {
  manifest = {
    "apiVersion" = "argoproj.io/v1alpha1"
    "kind"       = "ApplicationSet"
    "metadata" = {
      "name"      = var.project_name
      "namespace" = var.argo_namespace
    }
    "spec" = {
      "goTemplate" = true
      "goTemplateOptions" = [
        "missingkey=error"
      ]
      "generators" = [
        {
          "list" = {
            # Commenting out the following line stops the crash
            "elements" = [for environment in var.environments : { "environment" = environment }]
          }
        }
      ]
      "template" = {
        ... # Truncated for size
      }
    }
  }
}

Let me know if you'd like my crash output - I omitted it since it's pretty long, and the test case from @cherifsahraoui seems like it should suffice.

I had a similar issue with GKE and rolling back to 2.29.0 worked!

[maateen]

Rolling back to 2.29.0 worked for me as well.
