I am trying to retrieve customer data with customer Object.

Below is the code:-

protected $customerRepository;
public function __construct(
    \Magento\Customer\Api\CustomerRepositoryInterface $customerRepository,
) {
   $this->customerRepository = $customerRepository;

public function getUser($userId) {
    $customerObj = $this->customerRepository->getById($userId);
    $customerEmail = $customerObj->getEmail();
    $customerAmount = $customerObj->getAmount();

I am getting below error when used above code:-

 Uncaught Error: Call to undefined method 

So I am using below code now to get amount value by thinking amount value is not set for that customer:-

    $amount= '';
    $amount= $customerObj->getAmount();

Now I am getting below error:-

  PHP Fatal error:  Cannot use isset() on the result of an expression (you can use "null !== expression" instead)

How can I check the condition if that attribute value is not set, then I will set it as empty.

Is that can be checked? Please, anyone suggest me
