Here is example https://codesandbox.io/embed/jnnr090w8y

Can you provide more info about this error and maybe provide mini example?

maybe you should try to call setTime in componentDidMount, not in constructor can you check it?

i mean, that you should call this.props.timer. setTime(10000) in componentDidMount why are you calling reset? and Timer.Minutes component has no such property initialTime

Could you please tell what bundler are you using? webpack, vite? or maybe you are using create-react-app or next.js?

can you try version `^2.0.5`, please? if it will not help, i will try to reproduce this error with create-react-app
