I have below script for Angular promise.I have chained finally method with then bale.But some time I am getting error TypeError: Cannot call method 'finally' of undefined.

Here is the script :

someSerivces.getSomeMethod(someData)
    .then(
        function(data) {
            //success
        },

        function(error) {
            // rejection
        }

    ).finally(function() {
        //script
    });

GetSomeMethod :

someSerivces.getSomeMethod = function() {
        var deferred = $q.defer();

        otherService.httpCall({...})
        .then(
                function(response) {
                  deferred.resolve(response.data);
                },

                function(response) {
                  deferred.reject(response);
                }

            );

        return deferred.promise;
      };

I know its because of promise is not available for chaining.So,it getting such error.How I can hanlded this error ? Or is there any other way to handled it?

How I can handled this exception?

Show us `getsomeMethod` – Benjamin Gruenbaum Jul 01 '16 at 13:59
@BenjaminGruenbaum I have added generic script – RIYAJ KHAN Jul 01 '16 at 14:03

You get this error *"sometimes"*? Anyway, from your code - this is not possible what you are describing. – dfsq Jul 01 '16 at 14:04
What if the http call resulted in error and does not return promise? – RIYAJ KHAN Jul 01 '16 at 14:07

It doesn't even matter how http goes, because `getSomeMethod` returns promise *always*. So there is no way finally will be unavailable. So again - posted code can't result into error you describe. – dfsq Jul 01 '16 at 14:08

Also [avoid the deferred antipattern](http://stackoverflow.com/q/23803743/1048572)! – Bergi Jul 01 '16 at 14:26
