getUrl() on media collection not working

[Ikechukwu-Ezugworie]

I have a block of code that attaches the media to all model in a collection,
but the getUrl() method, throws a Call to a member function getUrl() on string

this is the code:

$managementPage = ManagementPage::get();
        foreach ($managementPage as $key => $value) {
            $managementPage[$key]->getFirstMediaUrl()->getUrl();
        }
        return response()->json([
            'data' => $managementPage
        ]);

here's the error:

 "message": "Call to a member function getUrl() on string",
    "exception": "Error",
    "file": "/Users/ik/Documents/Dev/City Gate Estate Web/admin-backend/app/Http/Controllers/ManagementPageController.php",
    "line": 20,

any help guys 🙏 on how to retrieve the media url on a collection

->getFirstMediaUrl() already returns a URL, as a string.

As a result, no method can be called after it, like you do in your example with ->getFirstMediaUrl()->getUrl().
