meanjs 0.4.0 not working when deployed to Heroku

[armedirken]

I've just tried the meanjs 0.4.0 in local host and runs fine but when I deploy to heroku (link to app here) and try the "Sign up" option I get this in the navegator console:

POST https://meanjsapptest.herokuapp.com/api/auth/signup 503 (Service Unavailable)

and when I write the comand heroku logs in the CLI I get:

I don't know what to do now because Heroku supports tell me thar the error is in my code but I haven't changed anything there!

[armedirken]

I had to change the node version in Package.js from ">=0.10.0" to "6.6.0" and now it's working fine.

[lirantal]

I'll update our engines to reflect 6.10, but where did you get that 0.4.0 version to begin with? this is the generator? because 0.10.0 seems rather an old entry

[armedirken]

Yes. The package.js showed a node version "node": ">=0.10.0" when I used the Yeoman generator.
