Error in AngularJS when attempting to add a new field within a for loop

I encountered an issue while attempting to add a new "field" into an array. It seems to stop at a specific number of objects within the array. For example, if my array contains 33 objects, the addition stops at the 7th object.

This is a snippet of my JavaScript code:

    if ($scope.all[i].CATEGORY == 'Community')
       {
           $scope.community.push($scope.all[i]);
           $scope.community[i].visibility = true;
           console.log($scope.community[i])
       }

The error message that I received is displayed here:

Note: The 'Visibility' attribute does not exist in my object; I am trying to insert it dynamically.

Additional information:

Upon logging the entire array, it shows all 33 objects present.

                if ($scope.all[i].CATEGORY == 'Community')
                {
                    $scope.community.push($scope.all[i]);
                    console.log($scope.community)                      
                }

However, when using the [i] loop for logging:

                if ($scope.all[i].CATEGORY == 'Community')
                {
                    $scope.community.push($scope.all[i]);
                    console.log($scope.community[i])  <----                    
                }

I get 6 valid returns and 27 undefined returns..

There are certain Objects that do not contain a property called "visiblility". You must be able to manage it with the code snippet provided below:

 if ($scope.all[i].CATEGORY == 'Community')
 {
    $scope.community.push($scope.all[i]);
    if($scope.community && $scope.community[i]){
    $scope.community[i].visibility = true;
    console.log($scope.community[i])
    }
}
