Redux-form-material-ui: Warning: Failed prop type: Invalid prop `value` of type `string` supplied to `Slider`, expected `number`.

I'm receiving the above error when using the slider component. I've used the component as follows:

<Field name='cycleValue' value={0} min={0} max={5000} step={10} component={ Slider } defaultValue={2500} />

When I check the initial value of the value prop initially after render, it's an empty string (""), which triggers the error. The defaultValue prop is ignored.

There are two other text fields that share the same name (and the same value). Despite the error the slider works normally and the values update on these components. I've also disconnected the slider from these other text fields, but the error persists.

Any suggestions? I feel though I may have missed an important step, but so far the other components in my forms have been working absolutely fine.

I've personally solved it in a similar way to how the DatePicker issue was solved:

<Field name='cycleValue' format={(value, name) => value === '' ? 0 : value} component={ Slider }/>
