Trying to get data from Odoo using PHP/Laravel-9 using XMLRPC

I am able to authenticate but when trying to get data it's giving me an error

This is the error I am getting.

I am using Laravel version 9.46, check using via php artisan -v

I am using "phpxmlrpc/phpxmlrpc": "^4.10" package

How can I authenticate and get the tickets and tasks data from Odoo?
