Create service instance failed due to BPEL error

I have uploaded a vFW and created a service instance based on the tutorial - Tutorial: Onboarding and Distributing a Vendor Software Product (VSP). I used POSTMAN to create an account as per the tutorial - Tutorial_vIMS: Create AAI cloud account.
However when I try to create a service instance in VID, I get the following error in the VID UI.

07/18/17 10:25:05 HTTP Status: Unknown (502)
{
  "serviceException": {
    "messageId": "SVC2000",
    "text": "Request Failed due to BPEL error with HTTP Status= %1 \nError occurred while executing the process: org.camunda.bpm.engine.exception.NullValueException: no processes deployed with key 'CreateServiceInstance': processDefinition is null",
    "variables": [
      "502"
    ]
  }
}

and when I look at the MSO BPMN log file I see the corresponding error:

2017-07-18T09:25:05.351Z|4fb5491b-40b5-49e3-8461-db8e12101f01|ENGINE-16004 Exception while closing command context: no processes deployed with key 'CreateServiceInstance': processDefinition is null

I am using ONAP version 1.1. Any suggestions what is wrong? Do I need to load a BPEL process definition?

Thanks
