cloudflare-go version

v0.89.0

Expected output

See on documentation (https://developers.cloudflare.com/api/operations/worker-script-get-settings), durable object have an optional script_name field :

The actual API usually return it but after after the binding using wrangler, the API doesn't return it.

$ curl "https://api.cloudflare.com/client/v4/accounts/{account_id}/workers/scripts/{script_name}/settings" -H "Authorization: Bearer XXX"                                                                    
{
  "result": {
    "placement": {},
    "compatibility_date": "2023-09-22",
    "compatibility_flags": [],
    "usage_model": "standard",
    "tags": [],
    "tail_consumers": [],
    "logpush": false,
    "bindings": [
      {
        "class_name": "Project",
        "environment": "production",
        "name": "DURABLE_OBJECT",
        "namespace_id": "XXX",
        "type": "durable_object_namespace"
      }
    ]
  },
  "success": true,
  "errors": [],
  "messages": []
}

This make the terraform-provider-cloudflare_v4.26.0 plugin crash, and make me unable to use terraform on my cloudflare env after adding a durable object binding using wrangler.

I'm not into go development but I've located the bug (https://github.com/cloudflare/cloudflare-go/blob/v0.89.0/workers_bindings.go#L506) and I think I just need to allow this value as optional.

I hope this can be resolved,

Error: The terraform-provider-cloudflare_v4.26.0 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.
