angularjs ng-repeat error-handling JavaScript

I'm integrating two systems and I've been struggling with this for a few days now and could really use some help. Hey everyone, I'm running into an issue that's driving me crazy... I'm experiencing strange behavior when using `ng-repeat` to display a list of complex objects in AngularJS 1.8. The objects are deeply nested, and while I can render simple properties without issues, accessing nested properties leads to `undefined` values on the first load. Here's a simplified version of my code: ```javascript $scope.items = [ { id: 1, details: { name: 'Item 1', description: 'Description 1' } }, { id: 2, details: { name: 'Item 2', description: 'Description 2' } } ]; ``` ```html <div ng-repeat="item in items"> <h3>{{ item.details.name }}</h3> <p>{{ item.details.description }}</p> </div> ``` Initially, this works fine, but if I later add a new item with a missing `details` object, like this: ```javascript $scope.items.push({ id: 3 }); ``` Now, when Angular tries to render the list, it throws an behavior: `want to read property 'name' of undefined`. I tried using the `ng-if` directive to check if `details` exists, but it doesn't seem to prevent the behavior. Here’s what I attempted: ```html <div ng-repeat="item in items"> <div ng-if="item.details"> <h3>{{ item.details.name }}</h3> <p>{{ item.details.description }}</p> </div> <div ng-if="!item.details"> <h3>Details not available</h3> </div> </div> ``` Unfortunately, the behavior continues. I've also checked to ensure that my `$scope.items` is properly initialized before rendering the template. Is there a more effective way to handle this situation without causing runtime errors? Any insights would be greatly appreciated! I'm working on a CLI tool that needs to handle this. I'd really appreciate any guidance on this. I'd love to hear your thoughts on this. I'm working in a Linux environment. Any feedback is welcome!
