I have a code with AngularJS:
service.doSomething()
.then(function(result) {
//do something with the result
});
In AngularJS 1.5.9 when I have error in the .then()
section like:
service.doSomething()
.then(function(result) {
var x = null;
var y = x.y;
//do something with the result
});
I'm getting clear error message:
TypeError: Cannot read property 'y' of null
But in version 1.6 with the same code I'm getting a different error:
Possibly unhandled rejection: {} undefined
I know that this is related to this change, and the single solution is quite simple by adding .catch()
block:
service.doSomething()
.then(function(result) {
var x = null;
var y = x.y;
//do something with the result
})
.catch(console.error);
Now I again have what I want:
TypeError: Cannot read property 'y' of null
But how to obtain the same result (more detailed error) for entire application without adding .catch()
block in every single place?
I tested the suggested solution to disable this by adding:
$qProvider.errorOnUnhandledRejections(false);
But with this the situation is even worse - I do not have ANYTHING in the console! The error is swallowed somewhere and not logged at all. I'm not sure is it a problem with AngularJS 1.6 or with my configuration.
Do you have any ideas how to "restore" logging behavior from version 1.5.9?
EDIT:
Adding custom error handler:
.factory('$exceptionHandler', function($log) {
return function(exception, cause) {
$log.warn(exception, cause);
};
})
does not help at all. In the error handler I already receive the "wrapped" error.
This has been fixed with fix($q): Add traceback to unhandled promise rejections -- Commit 316f60f and the fix is included in the v1.6.1 release.
