javascript - 创建 react 应用程序在代码重新加载时偶尔会随机崩溃

Question

这真是令人沮丧。我正在开发一个应用程序，这种情况在几周前开始发生，我无法确定原因。每隔一段时间，应用程序就会崩溃。如果我保存代码以触发重新加载，这种情况似乎会更频繁地发生，但它也可能在浏览器中浏览应用程序时随机崩溃。

据我所知，没有明显的错误，而且它是随机发生的。有时它会在一分钟内发生两次，有时它会持续 30 分钟而没有发生。由于我看不到任何错误，我所需要做的就是按 Control+C 并重新运行 npm start，但我的工作流程中断仍然令人沮丧。我唯一拥有的是控制台中的此错误消息:

assert.js:339
    throw err;
    ^

AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:

  assert(index !== -1)

有人对可能的原因或我如何进一步调试它有任何想法吗？
