未捕获错误：在 mousemove 事件中调用 chrome.storage.local.set 时扩展上下文无效

Question

你能再帮我解决这个问题吗？Uncaught Error: Extension context invalidated.我在 chrome://extensions 中遇到错误。

我正在尝试制作一个计时器，每当您空闲时，假设 5 秒就会触发警报，您​​需要移动鼠标来停止警报，并且我需要将其与其他打开的选项卡同步，这就是我使用的chrome.storage.onChanged.addListener原因谢谢wOxxOm的推荐。它工作得很好，但我收到了这个错误。
