Conflicting SSG Paths

Why This Error Occurred

You returned conflicting paths in your getStaticPaths function for one of your pages. All page paths must be unique and duplicates are not allowed.

Possible Ways to Fix It

Remove any conflicting paths shown in the error message and only return them from one getStaticPaths.

Example conflicting paths:

export default function Hello() {
  return 'hello world!'
}
export const getStaticProps = () => ({ props: {} })

export const getStaticPaths = () => ({
  paths: [
    '/hello/world', // <-- this conflicts with the /hello/world.js page, remove to resolve error
    '/another',
  ],
  fallback: false,
})

export default function CatchAllPage() {
  return 'Catch-all page'
}

Example conflicting paths:

export const getStaticPaths = () => ({
  paths: ['/blog/conflicting', '/blog/another'],
  fallback: false,
})

export default function Blog() {
  return 'Blog!'
}
export const getStaticProps = () => ({ props: {} })

export const getStaticPaths = () => ({
  paths: [
    // this conflicts with the /blog/conflicting path above, remove to resolve error
    '/blog/conflicting',
    '/another',
  ],
  fallback: false,
})

export default function CatchAll() {
  return 'Catch-all page'
}
