it runs locally on mac with no issue, any ideas?

@JustinM1 sorry about the late reply! This is an issue that seems to keep coming up but it should be fixed in 0.6.1. Can you confirm your app or a dependent is not depending on an earlier version?

[JustinM1]

@siemensikkema no prob. I know how it can be, especially around this time of year. Unfortunately, I think there is still an issue.

[siemensikkema]

Is this on a custom server? How are you building? Can you replicate this on your own machine? I see you're running swift 3.0.1, I doubt upgrading to 3.0.2 will help but it's worth a try.

EDIT: just read the title again where it clearly says Heroku.
