It seems like $config of type Magento\PageCache\Model\Config is incompatible with the declared type Magento\Framework\App\Config\ScopeConfigInterface of property $config.

The method getType() does not exist on Magento\Framework\App\Config\ScopeConfigInterface.

The method isEnabled() does not exist on Magento\Framework\App\Config\ScopeConfigInterface.
