Possibly unhandled rejection: {}

Question

I got the error:

Possibly unhandled rejection: {}

Answer 1

First option is simply to hide an error by disabling them with errorOnUnhandledRejections in $qProvider configuration:

app.config(['$qProvider', function ($qProvider) {
    $qProvider.errorOnUnhandledRejections(false);
}]);

BUT this will only switch off logging. The error itself will remain

The better solution in this case will be - handling a rejection with .catch() method:

service.doSomething()
 .then(function (response) {
   //normal processing
})
 .catch(function (err) {
     console.log(err);
     throw err;
});
