What is the reason behind AngularJS throwing an error related to bad augmentation?

Whenever I try to update the src link in my Angular code from version 1.2.2 to 1.5.0, I encounter an error. The code works perfectly fine with 1.2.2, but switching to 1.5.0 throws an error. I want to upgrade it to 1.5.0, so what changes do I need to make in the code to ensure compatibility with Angular 1.5.0?

Error: ng:areq
Bad Argument
Argument 'Controller_index' is not a function, got undefined
Description
AngularJS often checks for certain values using a helper function. If the check fails, this error is thrown. To resolve this, ensure that the expected value is defined and truthy. Even though I know 1.2.2 is outdated, I'm still using it and I am unsure of the necessary changes for 1.5.0. It seems correct to me based on my knowledge.

Answer №1

If you're seeing that error message, it typically indicates that you haven't properly registered Controller_index as a controller in your AngularJS application. You can fix this by adding the following code:

module.controller('Controller_index', Controller_index);

This change is important to note as it was introduced in the transition from version 1.2 to 1.3 of AngularJS.
