php8 error

Hi,

When trying the plugin with php8 we get this error:

An error of type E_ERROR was caused in line 52 of the file /www/canadaw_104/public/wp-content/plugins/packlink-pro-shipping/vendor/packlink/integration-core/src/Infrastructure/Utility/GuidProvider.php.

Is the plugin compatible with php8?

Thanks
