Slider Issue

Hello. I am trying to implement a slider feature for my PWM rate control (from 0-255).
However, when I try to create a Slider, it gives me an error, something about no override of that sort.

Here's my code of the Slider creation:
`
        <Slider
          value={data.pwmWeb}
          onChange={updateFormValue}
        />
`

UpdateFormValue is the same thing in the main branch.
