我有一个函数应用程序，其中的函数可将消息发送到事件网格。该函数应用程序已注册并获得RBAC授权。此同一函数应用程序中的函数已订阅此事件网格主题。当我将该应用程序发布到Azure并远程运行它时，它工作正常。但是当我在VS 2022中本地运行它调试时，我得到了未经授权的访问来发送消息。VS 2022中的调试对于我们所做的其他Azure相关的事情来说工作得很好。

当我在VS 2022的调试模式下执行函数应用程序以将数据发送到事件网格时，我收到未经授权的错误：

//Name of the endpoint of Event grid topic
    string topicEndpoint = transformAlgoSendRMessage_TopicEP;
    //Creating client to publish events to eventgrid topic
    EventGridPublisherClient client = new EventGridPublisherClient(new Uri(topicEndpoint), new DefaultAzureCredential());
    //Creating a sample event with Subject, Eventtype, dataVersion and data
    EventGridEvent egEvent = new EventGridEvent("TransformTelemetry", "TransformAlgorithm.broadcastTransform", "1.0", machinePartTransformTelemetry);
    // Send the event
    
    try
    {
        await client.SendEventAsync(egEvent);
        if (b_debug_contractor)
            log.LogInformation("SendRTransformMessage sent transformdata - PosX:" + machinePartTransformTelemetry[1]);
    }
    catch (Exception e)
    {
        log.LogError("Failed to send SendRTransformMessage. " + e.Message);
    }

未授权错误：
