Javascript 如何在浏览器中获取未处理承诺拒绝的来源？

我目前面临一个无法复制的错误

我的前端错误记录器是Bugsnag，前端使用Vue.js/Vue router/Vue apollo Graphql

我有时会在Bugsnag中出现错误，比如：

未处理的Rejection处理程序收到了一个非错误

。这样：没有文件，没有堆栈跟踪

出现此错误的用户操作是从一个页面转到另一个页面，每次都是相同的源和目的地，但我无法在本地或生产中复制。我不知道该用户是否被阻止，或者该错误是否对他没有影响

我尝试使用日志记录更多信息，但我得到的唯一信息是：

但当我创造自己的未经处理的拒绝承诺时，我可以得到这样的东西：

所以，我的问题是：

如何在浏览器中找到更多关于拒绝承诺的来源的信息？

查看所有

reject

调用和

throw

语句，找到使用非错误对象值的语句。一根短绒可能会对此有所帮助，尤其是当你使用typescript时。谢谢@Bergi。我已经在我们自己的代码库中搜索过了，我没有找到类似的东西。它可能在依赖项中，但使用的依赖项经过了很好的测试：Apollo、vue。。。我不认为我是唯一一个有这种感觉的人。顺便说一句，我们不使用类型脚本：（我想你只能尝试用

.catch（e=>{throw（e instanceof Error）？e:new Error（`unknown${e}位于文件x行y`）；}）乱丢你的承诺链。
