Error: Cannot read property 'speeds' of undefined when omitting duration

[crtl]

Hello,

Ive installed jquery.transit over npm and when calling the transition method on any element I get the following error:

> temp1.transition({x: 100})

Uncaught TypeError: Cannot read property 'speeds' of undefined
    at r.fn.init.$.fn.transition.$.fn.transit (jquery.transit.js:603)
    at <anonymous>:1:7

When adding the duration temp1.transition({x: 100}, 300) it works fine.
