Your error is more logic than syntax, if the customer isn't logged in (guest) you cannot get the user id. I would edit your helper function to check if the user is logged in and return false if not.

public function getCustomer()

 $customerSession = $this->customerSession->create();
 $customerData = $customerSession->getCustomerData();
 if($customerSession->isLoggedIn())
 return $customerData;
 else
 return false;
 

Then in your getTicket function use something like this :

if ($this->helperData->getCustomer())
 // run your code as normal
 else 
 // redirect to login
