Error: The terraform-provider-azurerm_v3.91.0_x5 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.

We found 9223372036854776000 is from one imported eventhub resource, which is created from azure portal with infinite retention time enabled. Here is the state file details.
        {
          "index_key": "<index_key>",
          "schema_version": 0,
          "attributes": {
            "capture_description": [],
            "id": "<id>",
            "message_retention": 9223372036854776000,
            "name": "<name>",
            "namespace_name": "<namespace_name>",
            "partition_count": 1,
            "partition_ids": [
              "0"
            ],
            "resource_group_name": "<resource_group_name>",
            "status": "Active",
            "timeouts": null
          },
          "sensitive_attributes": [],
          "private": "<private>"
        }

Also from provider document, maximum value of message_retention is 7 days, could be related to the error.
https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/eventhub#message_retention

Expected Behaviour

After imported the infinite retention time eventhub resource, no error should occur during terraform plan.

Actual Behaviour

provider plugin crashed.

Steps to Reproduce

1. create an eventhub with Infinite retention time enabled from azure portal
   

2. terraform import the resource

3. terrafrom plan

Hi @yueshao37 thanks for opening this issue. I would like to explain that Terraform performs CRUD management on Azure resources based on Azure Rest API. According to the API definition, the type of messageRetentionInDays is int64, and the maximum value of int64 should usually be 9223372036854775807. However, the 9223372036854776000 returned by the API is greater than 9223372036854775807. This is the root cause of the crash. Therefore, it is recommended to contact Microsoft Support to solve the problem of inconsistency between the API definition and the actual situation.

In addition, the crash occurred in terraform-plugin-sdk instead of terraform-provider-azurerm.
