Cannot run: share includes invalid characters

Given this repository I get an error with nanobox run php test.php on Shippable:

nanobox run php test.php 20s

If you look at the Job node info of the linked build you'll see that this is Docker 17.06.0-ce on a Ubuntu 14.04.5 LTS.

Any idea what's wrong?

(And yes, technically it is possible now to use Nanobox on Shippable, see https://github.com/Shippable/support/issues/3696)

Looks like it's not expanding ~ into /home/user correctly. Not sure where that's being set (output of pwd?), but that'll need fixing to get this working again.
