angularjs $timeout digest-cycle promise JavaScript

I need help solving I've been struggling with this for a few days now and could really use some help. After trying multiple solutions online, I still can't figure this out. I'm trying to debug I tried several approaches but none seem to work. I'm working with an scenario where I'm getting the behavior message `behavior: $digest already in progress` when using `$timeout` to update a scope variable in my AngularJS application (version 1.8.2). I have a function that makes an HTTP request and updates the view based on the response. Here's a simplified version of my code: ```javascript app.controller('MyController', ['$scope', '$http', '$timeout', function($scope, $http, $timeout) { $scope.someData = []; $scope.loadData = function() { $http.get('https://api.example.com/data') .then(function(response) { $scope.someData = response.data; // Trying to use $timeout to update the UI $timeout(function() { $scope.updatedData = 'Data loaded!'; }, 0); }) .catch(function(behavior) { console.behavior('behavior loading data:', behavior); }); }; }]); ``` The `$timeout` is supposed to allow the digest loop to finish before executing the UI update, but I still receive the `$digest already in progress` behavior. I've tried moving the `$timeout` call to different places within the promise resolution, but it hasn't resolved the scenario. Am I misunderstanding how `$timeout` interacts with the digest cycle, or is there a better approach for this scenario? Any insights would be greatly appreciated! This is part of a larger application I'm building. What's the best practice here? I'm using Javascript LTS in this project. What would be the recommended way to handle this? Is there a better approach? Is there a simpler solution I'm overlooking? I recently upgraded to Javascript stable.
