Question

Hi I was working on angular app after few changes I am getting an error which I am not sure why it's coming.

error : TypeError: a is not a function

I am not sure why this is coming and I am getting such 15 errors. It is not breaking my app but I am seeing this on chrome console.

I have changed from min.js to .js got this error :

As you cant place code in plunker I can only guess.

Are you passing any parameter to callback function? Usually it happens when you pass something like

.success($scope.message = "Task completed") 

to in-build angular functions. In above case when the Ajax call completes, it is being invoked as a function, thus causing the error. It should have been as

.success(function () {
    $scope.message = "Task completed";
})

In your case you may be assigning "a" to some variable.
