Can't throw error (reject promise) in response interceptor

[Astray-git]

Chrome will throw 'Uncaught (in promise)' if I return reject in response interceptor.`

when function takes 3 args: value, fulfilled, rejected, but is called with only 2, no rejected callback here:

I'm having this same problem. When using interceptors is there a way to get away with this Uncaught (in promise) message in console?

[steffans]

Currently it's not implemented that a interceptor can reject a Promise, what would you expect to happen after you returned a rejected Promise?

[victorwpbastos]

In fact, I just want to silence the errors in console.

@victorwpbastos Just catch the failed promise yourself and return the original response.
Something like this:

Vue.http.interceptors.push( (request, next) => {

    // do something with request

    next( response => {

            // will return the original response if the promise fails
            return someRejectedPromise().catch( () => response )

    });

});

@steffans It would be great to feed the error to raven-js

Currently using window.onunhandledrejection but it does not have yet browser support. Besides, I also don't like a 'catch all' solution that onunhandledrejection provides.

I still have no idea how could i perform Error Handling in interceptors... any hacks?

[tiagomatosweb]

So do I, I have tried a lot to do a catch all in the interception but no luck at all.
Does anyone have any clue?

I just created a pull request to let Promise rejections bubble up the chain, this makes it possible to catch the error using the standard .catchmethod. Please support the pull request to add this feature and make vue-resource's error handling easier.
