Answer 1

If you review the interface Magento specifies in the error message, you'll see there is indeed no getCustomerId accessor method. The correct accessor method is getId:

interface CustomerInterface extends \Magento\Framework\Api\CustomAttributesDataInterface
{

    ...

    /**
     * Get customer id
     *
     * @return int|null
     */
    public function getId();
