I think the following question may be relevant: https://stackoverflow.com/questions/46306997/syntaxerror-missing-after-argument-list-when-using-async

Your version of NodeJS (6.11 LTS) is too old and does not support the async/await features. The syntax error is a result of the Javascript interpreter not recognizing the async token and getting confused about arguments.

Upgrade to NodeJS 7.6 or later. https://www.infoq.com/news/2017/02/node-76-async-await
