Description

export const Select = () => (
	<OptionButton type="button" data-qa-id="listItem-btn" />
);

const Button = withTheme(styled.button<Theme>`
	width: 100%;
`);

export const OptionButton = styled(Button)`
	width: 50%;
`;

If I add Button directly - no error

If I remove withTheme - no error too

@Opty1712 did you found a work around for this?

Yesterday i took some time to debug this and found what is going on.

You have:

export const Select = () => (
	<OptionButton type="button" data-qa-id="listItem-btn" />
);

const Button = withTheme(styled.button<Theme>`
	width: 100%;
`);

export const OptionButton = styled(Button)`
	width: 50%;
`;

It looks that your Theme type is (when looking at the error)

interface Theme {
	type: string;
	"data-ga-id": string;
}

You need to make another type:

interface IWithTheme {
	theme: Theme;
}

and pass this on:

const Button = withTheme(styled.button<IWithTheme>`
	width: 100%;
`);

It wasn't obvious for me aswell, but withTheme HOC the theme is set in the theme prop.
Which is ofcourse logical, since you could also pass other props.
