Plugin crashes on openstack_containerinfra_cluster_v1

[dhrp]

Hi there,

I noticed this plugin crash error on using openstack_containerinfra_cluster_v1, and it explicitly asks to report plugin crashes.

Terraform Version

Oswald:tesla thatcher$ terraform -v
Terraform v1.0.2
on darwin_amd64
+ provider registry.terraform.io/terraform-provider-openstack/openstack v1.44.0

Affected Resource(s)

Please list the resources as a list, for example:

• openstack_containerinfra_cluster_v1

If this issue appears to affect multiple resources, it may be an issue with Terraform's core, so please mention this.

Terraform Configuration Files

resource "openstack_containerinfra_cluster_v1" "X" {
  name                = "X"
  cluster_template_id = "34af9035-edbc-4e97-96e3-d714eb963508"
  master_count        = 1
  node_count          = 1
  keypair             = "thatcher_oatcake"
}

Debug Output

Panic Output

If Terraform produced a panic, please provide a link to a GitHub Gist containing the output of the crash.log.

Expected Behavior

What should have happened?
Show plan output

Actual Behavior

Showed this error

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform apply (creates the cluster succesfully)
2. change a field (e.g. node_count)
3. terraform plan -> boom!

Important Factoids

Nothing crazy..

This appears to have been introduced v1.43.1 → v1.44.0 so I guess it's a plugin SDK upgrade issue.

For me this happen during 'destroy' command:

$ terraform -v
Terraform v1.0.11
on linux_amd64
+ provider registry.terraform.io/terraform-provider-openstack/openstack v1.45.0

$ terraform destroy
openstack_containerinfra_clustertemplate_v1.clustertemplate_1: Refreshing state... [id=...]
openstack_containerinfra_cluster_v1.cluster_1: Refreshing state... [id=...]

Fixed in v1.47.0 release - I didn't notice such an error anymore.
