I think the problem here is that the warning prevents the slider form rendering, which then causes the Error when the component tries binding to the non-existent slider. What are you passing to the range property of the component?

[Sateeshwaran]

same I'm also facing this issue. Below are the values that i'm passing
{{range-slider

            start= 20
           min=0
           max=100
           step=10
           connect=true
           on-change=(action "myAction")

}}

[miketervela]

@Sateeshwaran Are you passing in those constants, or binding to properties? If the range-slider tries to render before a computed property has a valid value, you could see that error.

Also, I'm not sure if you're getting the same warning as the original poster (range is not an object) or just the error in the issue title. If you are just referring to the "cannot read property 'on' of undefined" then look for a warning before it, which is the actual cause of the error:

In my case I was passing a number for @opacity, not [number]. Bad error messaging tbh.
