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
