Troubleshooting: AngularJS - Issues with nested controllers not functioning properly within ng-include

According to the AngularJS documentation (refer to nested controller fragment), I am attempting to implement nested controllers using ng-include

Main.html

<body id="spaWrapperApp" ng-app="spaWrapperApp">
        <div class="container-fluid" id="wrapper" ng-controller="mainController">
            <div class="navigation">
                <a href="javascript:void(0);" ng-click="requestPage('sample3_nestedApps_f1.html')">
                    <span>Page 1</span>
                </a>&nbsp;&nbsp;&nbsp;&nbsp;
                <a href="javascript:void(0);" ng-click="requestPage('sample3_nestedApps_f2.html')">
                    <span>Page 2</span>
                </a>&nbsp;&nbsp;&nbsp;&nbsp;
                <a href="javascript:void(0);" ng-click="requestPage('sample3_nestedApps_f3.html')">
                    <span>Page 3</span>
                </a>
            </div>
            <div id="content" >
                <div ng-include="currentPage"></div>
            </div>
        </div>

        <script type="text/javascript">
            window.spaWrapperApp = angular.module('spaWrapperApp',[]);

            spaWrapperApp.controller('mainController',['$scope',function($scope){

                $scope.currentPage = "sample3_nestedApps_f1.html";

                console.log($scope);
                $scope.requestPage = function(friendlyURL){
                    console.log(friendlyURL);
                    $scope.currentPage = friendlyURL;
                }
            }]);


        </script>
    </body>

Injected Page 1 Content (provided below) will be injected in ng-include

<div>Testing page include 1</div>
<hr/>
<br/>
<div ng-controller="FirstController">
    <p>1# {{ name }}</p>
    <div ng-controller="SecondController">
        <p>2# {{ name }}</p>
    </div>
</div>
<script type="text/javascript">
    spaWrapperApp.controller('FirstController',['$scope',function($scope){
        $scope.name = "FirstController Name";
    }]);
    spaWrapperApp.controller('SecondController',['$scope',function($scope){
        $scope.name = "SecondController Name";
    }]);
</script>

In this scenario, the final outcome is nested controllers being injected in the ng-include section.

The issue arises when running the code and an error message is displayed.

"Error: [ng:areq] Argument 'FirstController' is not a function, got undefined" 

Any insights on what might be causing this error?

Encountering an unexpected issue in AngularJS.

If you are utilizing ng-include and attempting to include pageX which contains some script, the script may not execute as expected. To resolve this, I moved all AngularJS controllers handlers into index.html and found that it resolved the issue for me. like

    window.spaWrapperApp = angular.module('spaWrapperApp',[]);
    spaWrapperApp.controller('mainController',['$scope',function($scope){
        $scope.currentPage = "sample3_nestedApps_f1.html";
        $scope.requestPage = function(friendlyURL){
            $scope.currentPage = friendlyURL;
        }
    }]);
    spaWrapperApp.controller('FirstController',['$scope',function($scope){
        $scope.name = "FirstController Name";
    }]);
    spaWrapperApp.controller('SecondController',['$scope',function($scope){
        $scope.name = "SecondController Name";
    }]);
