crash in raven.js when autobreadcrumbs.xhr is true in angular2 project

[rajendra2]

I started seeing following crash after upgrading to latest angular2/angular-cli and raven-js. I have narrowed the problem to be happening because of Raven.config().install(). I dont see the crash if I comment out this line.

The crash does not happen if I set autobreadcrumbs.xhr to null.

here is the version of the packages I am using:

"dependencies": {
"@angular/common": "2.4.1",
"@angular/compiler": "2.4.1",
"@angular/core": "2.4.1",
"@angular/forms": "2.4.1",
"@angular/http": "2.4.1",
"@angular/platform-browser": "2.4.1",
"@angular/platform-browser-dynamic": "2.4.1",
"@angular/router": "3.4.1",
"bootstrap": "3.3.7",
"core-js": "2.4.1",
"raven-js": "3.9.1",
"rxjs": "5.0.1",
"ts-helpers": "1.1.2",
"zone.js": "0.7.4"

Here is the stack trace in chrome:

Having the same issue.

@Starscream27 , here is one workaround I am using in the meantime.

var options = { 'release' : 'a2.1.0', 'autoBreadcrumbs':{'xhr':false}}
Raven.config(PUBLIC_DSN, options).install()

zone.js 0.7.2 works fine for me.
Seems zone.js 0.7.4 has issue.

[alexandrehebert]

@rajendra2 thanks, worked for me

[kiruto]

@rajendra2 worked for me! Thanks! !

To me this is not a bug in Raven, this is a real error (unhandled promise rejection) somewhere in your code that is being caught by Raven. I'm guessing this is caused by some AJAX library (jQuery?) that uses a Promise-based API, and the failed XHR is not being handled (e.g. .fail()).

@rajendra2 your fix worked for me, though is this going to stop sending error breadcrumbs to raven?

[QuentinFchx]

It has been reported on the zone.js project. You can track it here

[QuentinFchx]

The issue seems to have been fixed with [email protected]. Can you check and close accordingly?

[rajendra2]

@QuentinFchx , yes it seems to have fixed with [email protected]. I am not getting the crash anymore.
