What does status=canceled for a resource mean in Chrome Developer Tools?

Question

What would cause a page to be canceled? I have a screenshot of the Chrome Developer Tools.

Answer 1

If you make use of some Observable-based HTTP requests like those built-in in Angular (2+), then the HTTP request can be canceled when observable gets canceled (common thing when you're using RxJS 6 switchMap operator to combine the streams). In most cases it's enough to use mergeMap operator instead, if you want the request to complete.
