在“ PresentationConnection”上执行“发送”时出错：演示连接已断开

如何解决在“ PresentationConnection”上执行“发送”时出错：演示连接已断开

我正在做出 Chromecast发送器应用，并在发送** play / pause，seek，音量控制**的请求时出现以下错误：

df.astype(str).replace(regex='\d+',value='').sum(axis=1)

我已完全按照Google Chromecast文档中的说明进行操作。 链接：https://developers.google.com/cast/docs/chrome_sender/integrate

如果有人以前曾遇到问题或对此有任何想法，请帮忙。谷歌上对此也没有太多了解。

cast_sender.js:72 Uncaught DOMException: Failed to execute 'send' on 'PresentationConnection': Presentation connection is disconnected.

它有时会起作用，但怎么会，不知道。
