Problem with Stripe and CSFR (Laravel 5.6)

Hello!

I am having a problem with a Stripe form.

First say that I had my development environment in C9 and recently I have passed it to AWS-C9.

In the C9 environment it worked for me without any problem but in the AWS-C9 only Stripe is failing me.

It gives me a CSRF error even having the correct input field.

If I use middleware as Laravel documentation says:

https://laravel.com/docs/5.6/csrf

nothing happens, but if I add that middleware to the general configuration (that is, it affects everything) I get the following error

"Session store not set on request."

Then I tried to create a clean laravel from scratch and also in 5.6 and I got a simple Stripe form to work perfectly.

Does anyone know what can be due?

Thank you very much to all!
