You can try something like below.

protected $customer;

protected $customerFactory;

public function __construct(
    \Magento\Customer\Model\Customer $customer
    \Magento\Customer\Model\ResourceModel\CustomerFactory $customerFactory
)
{
    $this->customer = $customer;
    $this->customerFactory = $customerFactory;
}

$customerId = "1";
$customer = $this->customer->load($customerId);
$data = "customer attribute value";
$customerData = $customer->getDataModel();
$customerData->setCustomAttribute('customer_attribute_code',$data);
$customer->updateData($customerData);
$customerResource = $this->customerFactory->create();
$customerResource->saveAttribute($customer, 'customer_attribute_code');

It will work fine. Please check and let me know still you got the error.

Also, you can download extension which is already developed.

Thanks
