[SF 5.3.6 + EasyAdmin 3.5] Invalid CSRF token.

[S-Tian86]

Hi, I have a new problem,

I don't know if it's about the Symfony side or some EasyAdmin configuration.

When submitting any form in EasyAdmin tells me that Invalid CSRF token.

I don't even know how to debug it, anyone who can guide me how I can debug this error?

I tried to set csrf_protection: false in packages/framework.yaml but it gives me error because EasyAdmin needs that service.

Maybe this issue #41707 is related, but I don't use "remember me".

Thx for any helps.

To test, I changed the way to authenticate and did it the old way (GuardAuthenticator) and now I had no problems with the CSRF token.

Any idea what could be the problem?

@javiereguiluz maybe you can guide me, because I do not know if it is a Symfony problem, EasyAdmin or some misconfiguration of mine.

Edit: I include more information

At the time of login, this is the information that CsrfTokenBadge has in Symfony\Component\Security\Http\EventListener\CsrfProtectionListener

CsrfProtectionListener.php on line 49:
Symfony\Component\Security\Http\Authenticator\Passport\Badge\CsrfTokenBadge {#345 ▼
  -resolved: false
  -csrfTokenId: "authenticate"
  -csrfToken: "5eae9c3b469fa9913ed75c83b8ec9c._akSUptNTdY3jSc7NBYKJGl12RCExvgcOgvPt1eCrUE.hPpCOchgBINO-kpkfWdHSCIz7Ebdo4pdVziC8mDb-zCZ-mUG6gocsnzJHw"
}

but, when submitting any form:

CsrfProtectionListener.php on line 49:
Symfony\Component\Security\Http\Authenticator\Passport\Badge\CsrfTokenBadge {#541 ▼
  -resolved: false
  -csrfTokenId: "authenticate"
  -csrfToken: null
}

So, I don't know why crsfToken is null.

Thank you very much in advance to anyone who can guide me.
