terraform-provider-cloudstack_v0.5.0 plugin crashed while trying to read datasource

[rakesh-p]

I have a simple main.tf as follows that includes a data resource.
this plugin crashes when i run terraform plan
I have the correct values for api_key and secret as i could create a VM by not using "data resource"
What is that i am doing wrong please?

main.tf

terraform {
  required_version = ">= 1.6.6"
  required_providers {
    # Configure the CloudStack Provider
    cloudstack = {
      source  = "cloudstack/cloudstack"
      version = "0.5.0"
    }
  }
}

provider "cloudstack" {
  api_url    = "https://xxx.xxx.net/api"
  api_key    = "MY_KEY"
  secret_key = "MY_SECRET"
}


data "cloudstack_zone" "zone-data-source" {
  filter {
    name  = "regionid"
    value = 3
  }
}

terraform plan output:

data.cloudstack_zone.zone-data-source: Reading...

Planning failed. Terraform encountered an error while generating this plan.

Error: The terraform-provider-cloudstack_v0.5.0 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.

Hi @rakesh-p The datasource is working fine

Please find the sample code

provider "cloudstack" {
  api_url    = var.cloudstack_api_url
  api_key    = var.cloudstack_api_key
  secret_key = var.cloudstack_secret_key

}


data "cloudstack_zone" "zone-data-source" {
  filter {
    name  = "name"
    value = "ref-trl-6530-k-Mol8-kiran-chavala"
  }
}


output "zonedetails" {
value = data.cloudstack_zone.zone-data-source.dns1
}

terraform apply

zonedetails = "10.0.32.1"

I could get the following zone details

name 
dns1 
internal_dns1 
network_type
