streamDocument() with streamonly method returns an error

[siddharthlatest]

Adding streamonly field to the streamDocument() throws a syntax error.

appbaseObj.streamDocument({
  type: "tweet",
  id: "1",
  streamonly: "true"
}).on('data', function(res) {
  console.log("data update: ", res);
}).on('error', function(err) {
  console.log("streaming error: ", err);
})

Stacktrace:

Uncaught SyntaxError: Unexpected token ,conn.onmessage @ appbase.js:483

This is true for streamSearch() method as well.
