Laravel Redirect Not working even after defining correct route

Not sure what is wrong in my code but this line is not redirecting.

if ( $current_SIL_available_user < $number_wil_physical_delivery ) {
                    return redirect()->route( 'request_physical_delivery' )
                                     ->with( 'msg', 'Not enough amount' );

                }

Here is Laravel Debugger output. As you can see it is setting session variable but NOT redirecting
