On one of your page's components you attached either getStaticProps
, getStaticPaths
, or getServerSideProps
as a member instead of as a separate export.
These methods can not be attached in the same way as getInitialProps
and must be their own export
Move the method to it's own export from your page.
Before
function Page(props) {
return <p>hello world</p>
}
Page.getStaticProps = () => ({
props: {
hello: 'world',
},
})
export default Page
After
function Page(props) {
return <p>hello world</p>
}
export default Page
export const getStaticProps = () => ({
props: {
hello: 'world',
},
})
