我一直在实施授权步骤，我使用fragsalat对THIS问题的答案进行了建模。
一切正常，直到到达
return new Redirect('login');
我得到错误：
aurelia-logging-console.js:47 ERROR [app-router] Error: Expected router pipeline to return a navigation result, but got [{"url":"login","options":{"trigger":true,"replace":true},"shouldContinueProcessing":false}] instead.
at processResult (aurelia-router.js:1761)
at aurelia-router.js:1725
at <anonymous>
我不确定为什么这不仅仅是重定向？
这是完整的app.ts文件，因此您可能会看到上下文：

答案 0 :(得分：1)
在您使用.slice的所有其他管道步骤中，它应该是相同的情况，因为管道步骤需要parseFloat(data.median_price.replace('$', ''));
作为返回值，但您返回return next.cancel(new Redirect())这里。
尝试将其更改为
Next
