Cannot read property 'route' of undefined

I have set my back link on a navbar , when I click to go back, it reroutes, but I do get the following in console:

Uncaught TypeError: Cannot read property 'route' of undefined
    at Router.back (back.js:719)
    at afterAnimation (back.js:440)
    at eval (back.js:480)

What does your routes.js look like? How are you calling the page that produces the error?

I need to look into that. Can’t say with certainty, but I think I didn’t mess with routs that much. Anyway, after I check, I’ll get back with my code and some more details.
Thanks.

Did you ever figure out what the problem was? Im trying to do the same and im getting the same error.
