Invalid_client error in league / oauth2

Hi, using the PHP library, I got the following error:
Fatal error: Uncaught League \ OAuth2 \ Client \ Provider \ Exception \ IdentityProviderException: invalid_client in /var/www/vhosts/malvon.es/…/vendor/league/oauth2-client/src/Provider/GenericProvider.php:222 Stack
Can someone help me?

Hey @jorge

Can you please share with us the parameters you are passing to the function call?

The error seems pretty explicit: invalid_client, you should verify you are passing the valid OAuth2 id and secret.

Kind regards,
Maximilien
