Use Alibaba Cloud's voice service to get the receipt message. When there is a message in the queue of Alibaba Cloud, no error is reported. When the queue is empty, an error seems to be reported. The problem is not sure, so I would like to ask if there is a way to judge the queue. If there is any news in it, please enlighten me.
