options.process undefined, even though it's not

[trydalch]

I'm currently trying to migrate from grunt-typescript to grunt-ts. I have all the other tasks working as expected right now, but when trying to use a process function in the concat task, it's undefined and fails. When I comment out the options block, it executes successfully.

What's wrong here?

grunt-ts version: 5.5.1

grunt-contrib-concat version: 0.4.0

I missed the var path = require("path"); line at the top of the old gruntfile 🤦
