passkit-generator: Can't generate boarding pass

Hi,

I’ve hit a problem trying to generate a boarding pass.

I have managed to generate a sample event type pass with no problem at all. It’s just the boarding pass that is giving me problems.

I’m seeing this error:

Schema validation failed due to error: "transitType" is not allowed +0ms

I do have transitType in the boadingPass object as you can see in my JSON

    ]
  }
}

if I omit transitTyoe (as a test) I get this error instead:

UnhandledPromiseRejectionWarning: Error: Error: Cannot proceed with pass creation. transitType field is required for boardingPasses.

I’m using v 1.6.4 with Node 8.10.0

Do you have any idea what I am doing wrong here?
