Encountered a Error: [$injector:modulerr] while integrating Angular JS with the mysterious Planet 9

I encountered an error after implementing AngularJS in Planet 9. Planet 9 is a tool built on top of SAP UI5, offering drag and drop functionality as well as the ability to include HTML, CSS, and JavaScript. I needed to use ng-repeat for an application, so I decided to integrate AngularJS for routing within that tool instead of using the route from AngularJS directly. Despite following suggestions on Stack Overflow to add ngRoute, the issue persisted even after integration. It seems like the Angular application may be trying to initialize before the AngularJS script fully loads, causing related functionalities not to work properly. At times, depending on internet speed, it might work. I also considered manually bootstrapping the Angular application, but the tool already included ng-app="angularApp" by default. I'm unsure about what's causing this error and whether manual bootstrapping would resolve it - if so, how can I remove the initial auto bootstrap of ng-app and do a manual bootstrap once the required AngularJS is loaded.

This is what the module looks like:

var angularApp =  angular.module('angularApp', ['ui.bootstrap']);

//and one of the controllers looks like this
angular.module('angularApp').controller('MainController', MainController);
MainController.$inject = ['$scope','$rootScope','$http'];

function MainController($scope, $rootScope,$http) {
    $scope.goToNW = function(){
        oApp.to('networkVisibility');
        angular.element('#Home-inner').removeClass();
    };
    //other controller functions...
}

The problem arises when using Angular version 1.6.9; the application fails to load itself. Using version 1.5.7 can lead to intermittent loading issues, sometimes successful and sometimes not, accompanied by the following error message:

Uncaught Error: [$injector:modulerr] Failed to instantiate module angularApp due to:
Error: [$injector:nomod] Module 'angularApp' is not available! You either 
misspelled the module name or forgot to load it. If registering a module 
ensure that you specify the dependencies as the second argument.
http://errors.angularjs.org/1.5.7/$injector/nomod?p0=angularApp

Note: The application tends to load without errors when the developer tools window is not open. However, opening the developer tools window and attempting to load the application results in the above error occurring three out of four times.

This is how the page source code appears after running the application:

Consider organizing your Angular app definitions in a separate file for better structure:

<script src="/public/neptune/p9library.js"></script>
<script id="sap-ui-bootstrap" type="text/javascript" src="/public/openui5/1.52/sap-ui-core.js" data-sap-ui-xx-bindingSyntax="complex" data-sap-ui-noDuplicateIds="false" data-sap-ui-preload="async" data-sap-ui-theme="sap_belize" data-sap-ui-libs="sap.ui.layout,sap.ui.unified,sap.ui.table,sap.m"></script>

<script src="/media/root/abcdef/js/angular.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/allmighty-autocomplete/1.0.140706/autocomplete.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/tether/1.4.4/js/tether.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js" integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl" crossorigin="anonymous"></script>

<!-- Load your Angular app by including this line -->
<script src="angularApp.js"></script>

Additional Recommendations:

To define your module, store it in an angularApp variable as shown here:
```
angularApp = angular.module('angularApp', ['ui.bootstrap']);
```

Check for ambiguous dependency injections within the MainController:

MainController.$inject = ['$scope','$rootScope','$http','mainService'];

and

MainController.$inject = ['$scope','$rootScope','$http'];

To begin with, my recommendation would be to rearrange any elements that rely on Angular so they are set after the angular script. This way, Angular will have loaded first and prevent any issues with loading components that require it.

<html>
    <title></title>
    <head>
        <!-- If p9library requires AngularJS, then move it below -->
        <!-- Non AngularJS required imports -->
        <script src="/public/neptune/p9library.js"></script>
        <!-- AngularJS -->
        <script src="/media/root/abcdef/js/angular.js"></script>
        <!-- AngujarJS required imports -->
        <!-- Links -->
    </head>
    <body class="sapUiBody" role="application" id="body" ng-app="angularApp">
        <script>
            //Code snippets removed for brevity
            var angularApp = angular.module('angularApp', ['ui.bootstrap']);
            //Changed how this is accessed.
            angularApp.controller('BOController', BOController);
            function BOController($scope,$rootScope, $http, mainService) {
                //Controller actions here
            }
            //Best practice to do this after function definition
            BOController.$inject = ['$scope','$rootScope','$http','mainService'];

            //# sourceURL=abcdef11.js
        </script>
    </body>
</html>

Another suggestion would be to separate the script code into its own file and utilize <script></script> tags for compilation. This can assist in troubleshooting and debugging processes in the future. Although not mandatory, it is considered a good practice.

Furthermore, ensure that the opening <html> and <head> tags are included in your code as they seem to be missing from what you provided. Please verify this before proceeding.

Feel free to test out these recommendations. In case of any issues, feel free to leave a comment for further assistance.

In my opinion, it is advisable not to insert any content into the DOM element when using planet 9. Many UX frameworks have functionalities that automatically replace the content within the tags.

<body class="sapUiBody" role="application" id="body" ng-app="angularApp">

I strongly believe that doing so could result in the replacement of DOM content within the body tag, potentially causing your angular code to be deleted and resulting in an error.
