Using ACF get_field causes infinite recursion

[Cesar Lopez]

I am trying to get the secret key configured in a setting using the ACF plugin (https://www.advancedcustomfields.com/)
But I notice, when the auth token is received and the get_field is called, there is an infinite loop that breaks the site.

 add_filter( 'graphql_jwt_auth_secret_key', function() {
            return get_field( 'jwt_auth_secret_key', 'option' );
        });

Stacktrace:

Any comment?
