The same problem of bundle.js. I saw your fix but didn't worked.I tried to move to older versions that uses java 8 but continue to fails. Always the same of bundle.js. And as you use MAC Os. I don't know what could be missing on my windows 10. I have all requirements installed and even others for others web projects plays. But I just get the same error. So if you could share the Js build. I will feel very thankful to you.
