Terraform- Azure Event Grid Subscription with Event hub endpoint

Question

Doing Event Grid Subscription with a EventHub endpoint

resource "azurerm_eventgrid_system_topic_event_subscription" "example" {
  name                = "example-event-subscription"
  system_topic        = azurerm_system_topic.example.name
  resource_group_name = azurerm_resource_group.example.name

  eventhub_endpoint {
    eventhub_endpoint_id = azurerm_eventhub.example.id
  }

I got the error like

Blocks of type "eventhub_endpoint" are not expected here.

Not sure what I'm missing here. Is the eventhub_endpoint is not a valid one ? How can i configure the eventhub for my event grid sub ?

Regarding the issue, please update your script as

resource "azurerm_eventgrid_system_topic_event_subscription" "example" {
  name                = "example-event-subscription"
  system_topic        = azurerm_eventgrid_system_topic.example.name
  resource_group_name = azurerm_resource_group.example.name

  eventhub_endpoint_id = azurerm_eventhub.example.id
}

For more details, please refer to here.

For example (I use terraform 0.15.4 on windows)

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "=2.46.0"
    }
  }
}
provider "azurerm" {

   
        subscription_id = "e5b0fcfa-e859-43f3-8d84-5e5fe29f4c68"
        client_id = "42e0d080-b1f3-40cf-8db6-c4c522d988c4"
        client_secret = "Gbx2eK64iqq_g_3NCA.ClJDfQpIjoae:"
        tenant_id = "e4c9ab4e-bd27-40d5-8459-230ba2a757fb"
        features {}
