Call to undefined method Magento\Customer\Model\ResourceModel\CustomerRepository\Interceptor::getByEmail() Call to undefined method Magento\Customer\Model\ResourceModel\CustomerRepository\Interceptor::getDataModel() ,

Answer 1

Use get() instead of getByEmail()

Replace This line :

$customer = $this->customerRepository->getByEmail($email);

With this one :

        try {
            $customer = $this->customerRepository->get($email);
        } catch (\Exception $exception) {
            echo $exception->getMessage();
        }

The Above code will through Eception if no customer found witht he email provided

* @throws \Magento\Framework\Exception\NoSuchEntityException If customer with the specified email does not exist.
     * @throws \Magento\Framework\Exception\LocalizedException

Answer 2

There is an issue with the usage of CustomerRepositoryInterface in your code. The getByEmail and getDataModel methods are not part of the CustomerRepositoryInterface.

<?php

namespace test\Org\Controller\Result;

use Magento\Framework\App\Action\Context;
use Magento\Framework\View\Result\PageFactory;
use Magento\Framework\Controller\Result\JsonFactory;
use Magento\Framework\HTTP\Client\Curl;
use Magento\Customer\Api\CustomerRepositoryInterface;
use Magento\Customer\Api\Data\CustomerInterfaceFactory; // Add this line

class Result1 extends \Magento\Framework\App\Action\Action
{

    /**
     * @var Magento\Framework\View\Result\PageFactory
     */
    protected $resultPageFactory;
    protected $curl;
    protected $resultJsonFactory;
    protected $customerRepository;
    protected $customerInterfaceFactory; // Add this line

    /**
     * @param Context $context
     * @param PageFactory $resultPageFactory
     */
    public function __construct(
        Context $context,
        Curl $curl,
        PageFactory $resultPageFactory,
        JsonFactory $resultJsonFactory,
        CustomerRepositoryInterface $customerRepository,
        CustomerInterfaceFactory $customerInterfaceFactory // Add this line
    ) {
        $this->curl = $curl;
        $this->resultPageFactory = $resultPageFactory;
        $this->resultJsonFactory = $resultJsonFactory;
        $this->customerRepository = $customerRepository;
        $this->customerInterfaceFactory = $customerInterfaceFactory; // Add this line
        return parent::__construct($context);
    }

    public function execute()
    {
        $email = $this->getRequest()->getParam('email');
        $result1 = $this->resultJsonFactory->create();
        $resultPage1 = $this->resultPageFactory->create();

        $URL = 'apiurl';
        $this->curl->setOption(CURLOPT_HEADER, 0);
        $this->curl->setOption(CURLOPT_TIMEOUT, 60);
        $this->curl->setOption(CURLOPT_RETURNTRANSFER, true);
        $this->curl->setOption(CURLOPT_CUSTOMREQUEST, 'GET');
        $this->curl->addHeader("Content-Type", "application/json");
        $this->curl->get($URL);
        $response = $this->curl->getBody();

        $customer = $this->customerRepository->get($email); // Use get instead of getByEmail

        // Use CustomerInterfaceFactory to create a new CustomerInterface instance
        $customerData = $this->customerInterfaceFactory->create();
        $customerData->setCustomAttribute('fin_cus_id', 'c123');
        $customer->updateData($customerData);
        $this->customerRepository->save($customer);

        $resp = json_decode($response, TRUE);
        $block = $resultPage1->getLayout()
            ->createBlock('test\Org\Block\Index')
            ->setTemplate('test_Org::result1.phtml')
            ->setData('model', $resp['model_list'])
            ->toHtml();

        $result1->setData(['output' => $block]);
        return $result1;
    }
}

In this code, I've replaced getByEmail with get to retrieve the customer by email. Additionally, I've used CustomerInterfaceFactory to create a new instance of CustomerInterface to set the custom attribute.
