AngularJS 1.8: Difficulty with $http interceptors affecting response processing
I'm experimenting with I tried several approaches but none seem to work. I'm working with an scenario with AngularJS 1.8 where my $http interceptors seem to be interfering with the processing of responses in my application. I have a service that makes a GET request to fetch user data, but the data is sometimes not processed correctly due to the way I’ve implemented the interceptor. Here’s what my interceptor looks like: ```javascript app.factory('httpInterceptor', function() { return { response: function(response) { // Adding a property to the response object response.data.modified = true; return response; }, responseError: function(response) { return Promise.reject(response); } }; }); ``` I’ve registered the interceptor in the config like this: ```javascript app.config(function($httpProvider) { $httpProvider.interceptors.push('httpInterceptor'); }); ``` Now, in my service, I make an HTTP GET request like this: ```javascript app.service('UserService', function($http) { this.getUser = function() { return $http.get('/api/users/1') .then(function(response) { console.log(response.data); return response.data; }); }; }); ``` When I call `UserService.getUser()`, I occasionally see that `response.data` does not include the `modified` property, especially under certain network conditions. Sometimes, it throws an behavior saying `want to read property 'modified' of undefined`. I can’t seem to pinpoint why this is happening. I suspect it might have to do with how the interceptor modifies the data or how promises are handled, but I need to find a clear answer. I've tried debugging the interceptor by adding console logs, and I do see it gets executed, but the modifications sometimes don’t reflect in the resolved promise. I would appreciate any insights on why this might be occurring and how I can ensure that the response data is consistently modified as expected. Is there a better approach? I'd be grateful for any help. For context: I'm using Javascript on Ubuntu 22.04. This is part of a larger service I'm building. I'd be grateful for any help.
