Debug Output

Panic Output

Error: Provider produced inconsistent final plan

When expanding the plan for module.kubernetes_module.google_container_cluster.gke_cluster to include new values learned so far during apply, provider "registry.terraform.io/hashicorp/google" produced an invalid new value for .network: was cty.StringVal("mutillidae-vpc"), but now cty.StringVal("https://www.googleapis.com/compute/v1/projects//global/networks/mutillidae-vpc").

This is a bug in the provider, which should be reported in the provider's own issue tracker.

Expected Behavior

The module would create the Kubernetes cluster, then the Kubernetes nodes

Actual Behavior

The build stopped when the panic error message appeared

Steps to Reproduce

Run terraform apply
