    session( 'message' ) is null so when you use session( 'message' )['status'] === 'success' you get that error.

    Verify the array exists before using it

    <div class="col-md-4 mt-step-col last {{ ((session('message')['status'] ?? '') === 'success') ? 'done' : '' . isActive( 'admin.installer.complete' ) }}">

    You could also use the native ‘dot’ notation to retrieve the ‘status’ element from ‘message’ to avoid the error of trying to access null as an array:

    session('message.status') === 'success'
