customer_index_index: Please correct the XML data and try again. in Magento 2

Question

I have created custom customer attribute by using new module and run the InstallData.php -

namespace mynamespace\modulename\Setup;
use Magento\Customer\Model\Customer;
use Magento\Customer\Setup\CustomerSetup;
use Magento\Customer\Setup\CustomerSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
class InstallData implements InstallDataInterface {
/**
 * Customer setup factory
 *
 * @var \Magento\Customer\Setup\CustomerSetupFactory
 */
private $customerSetupFactory;
public function __construct(CustomerSetupFactory $customerSetupFactory) {
 $this->customerSetupFactory = $customerSetupFactory;
}
public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context) {
 $setup->startSetup();
 /** @var CustomerSetup $customerSetup */
 $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
 $customerSetup->addAttribute(Customer::ENTITY, 'service_agreement', [
 'type' => 'int',
 'input' => 'select',
 'position' => 25,
 'label' => 'Service Agreement',
 'required' => false,
 'sort_order' => 120,
 'source' => 'Magento\Config\Model\Config\Source\Yesno',
 'visible' => true,
 'system' => false ]
 //'is_used_in_grid' => true,
 //'is_visible_in_grid' => true,
 //'is_filterable_in_grid' => true,
 //'is_searchable_in_grid' => true]
 );
 // add attribute to form
 /** @var $attribute */
 $attribute = $customerSetup->getEavConfig()->getAttribute('customer', 'service_agreement');
 $attribute->setData('used_in_forms', ['adminhtml_customer', 'customer_account_create']);
 $attribute->save();
 $setup->endSetup();
}

}

using magento setup:upgrade it installed and attribute created but when I going to "All customer" section from admin section its give me 500 error. As I check in log file its showing below error -

• Atul: @raphael if this is duplicate, can you plz share the link of original one with answer.

• Atul: I have updated version 2.1.4, and I disabled the own created module and run upgrade and refresh the cache but still same .
• Raphael at Digital Pianism: I've reopened the question then
• Atul: It run perfect if i m deleting newly created attribute from 'eav_attribute' table. means bug is in my code. In module I have created - registration.php, Setup/InstallData.php , etc/module.xml

You should use Magento\Eav\Model\Entity\Attribute\Source\Boolean source instead of 'Magento\Config\Model\Config\Source\Yesno'
