title: Receiving NPM err: Unexpected string in JSON at position 20938 within an ionic 3 project
body: <p>Not sure where the error is. (* is where private project information is held, i.e. Facebook app id and the app name) I have been receiving this error for a while now and I can't figure it out, is there something I'm missing?  </p>

  <p>Or could this be an error with my node or NPM? It would be nice to have some fresh eyes to have a look</p>
