Parser crashes on service.parser.js:51

[karellodewijk]

var parameterType = parameter.type.typeName;

This cannot be resolved when parameter.type is undefined. I resolved it with an "if (!parameter.type) return false;", but I'm asuming something went wrong earlier.

Output + Error + Stacktrace:

Before the crash parameter contained this:

NodeObject {
  pos: 339,
  end: 352,
  flags: 0,
  transformFlags: undefined,
  parent: undefined,
  kind: 145,

  modifiers:
   [ TokenObject { pos: 339, end: 347, flags: 0, parent: undefined, kind: 111 },
     pos: 339,
     end: 347 ],
  dotDotDotToken: undefined,
  name: IdentifierObject { pos: 347, end: 352, flags: 0, parent: undefined, text: 'path' },
  questionToken: undefined,
  type: undefined,
  initializer: undefined,
  _children:
   [ NodeObject {
