title: 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:
```jsx filename="pages/hello/world.js"
export default function Hello() {
return 'hello world!'
}
```
```jsx filename="pages/[...catchAll].js"
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:
```jsx filename="pages/blog/[slug].js"
export const getStaticPaths = () => ({
paths: ['/blog/conflicting', '/blog/another'],
fallback: false,
})
export default function Blog() {
return 'Blog!'
}
```
```jsx filename="pages/[...catchAll].js"
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'
}
```
