isNextPath error thrown inside session.js

[theednaffattack]

I'm having a weird issue with next-routes. session.js is throwing an error on line 21, a method named isNextPath.

My console's giving me: "TypeError: routes.isNextPath is not a function".

Commenting out the if statement it's wrapped in eliminates the error but it appears to be setting up the initial session so I'm guessing that's a bad idea. I'm not sure how to debug this since it's throwing an error due to a next.js package.

Any pointers you can suggest are much appreciated.
