serialOpen not working on Resin.io

[cSchubes]

Hi,

I am trying to use Bonescript on a BeagleBone black running resinOS. I install it with yarn, and then import it using a typical require statement. Calls to pinMode and digitalWrite are working fine. I encounter issues with serialOpen when I do:

bonescript.serialOpen('/dev/tty04', { baudRate: 112500 });

This returns the error:

TypeError: Cannot read property 'path' of undefined
  at Object.newFunction [as serialOpen] (/usr/src/app/node_modules/bonescript/src/my.js:451:31)
  at Object.m.doOpen (/usr/src/app/node_modules/bonescript/src/serial.js:16:28

I took a look at the source and couldn't seem to figure out what was happening with the path property. I have tried different options, different ttys, and dropping the leading zero in the port to no avail. Any help is greatly appreciated!
