Tenter de lire la propriété "En-têtes" sur chaîne
Well in my case, the error happened in my middleware called
AuthenticationMiddleware when i tried the example below:
I was giving a return of a response without using the Response method.
Error : return "Welcome, " . $request->session()->get('user')->name
Solution: return Response("Welcome, " . $request->session()->get('user')->name);
