What could be the reason for the 419 error (page expired) when sending a post request?

Question

CSRF

We have the usual form, with a token and a POST request. In response, I get 419 | Page expired.
I rummaged through the whole Google, tried everything I could, everywhere, in principle, the same thing. The project is new, I am writing from scratch for the first time, maybe I forgot something in the initial settings? What other data is needed to help debug?

Answer 1

419 error says that the CSRF token sent by the form is outdated, missing or incorrect
I think it's worth digging into whether the token is being passed, and also see what you have as a session driver

Answer 2

You need to issue a CSRF token. This is a defense against csrf attacks. Use the @csrf directive inside
your html form, you can read more here https://laravel.com/docs/8.x/csrf
