Azure IoTHub Event Hub Endpoint Creation is Unreachable

Question

Creating Event Hub Endpoint via Terraform it shows the status as "Unreachable" and "Unauthorized". But the same Endpoint when created manually seems to be working fine as expected. I would like to know if this can be a bug or am I missing out something?

Event Hub Endpoint via Terraform:

resource "azurerm_iothub_endpoint_eventhub" "jd-endpoint" {  
  resource_group_name = data.azurerm_iothub.jd-iot.resource_group_name  
  iothub_id           = data.azurerm_iothub.jd-iot.id  
  name                = "jd-endpoint"  
  connection_string = azurerm_eventhub_authorization_rule.staging.primary_connection_string  
}  

Provider Version:

terraform {  
  required_providers {  
    azurerm = {  
      version = "~> 3.24.0"  
    }  
  }

But the same Endpoint when created manually seems to be working fine as expected.

You mean, under IoT Hub routing?

Can you please confirm, If the endpoint uses managed identity? If yes, please check that the IoT Hub principal has the required permissions on the target.
