# Error: Static generation failed for path '/[slug]' because 'generateStaticParams' did not return a value for slug '...'

- **ID:** `nextjs/static-generation-failed-for-dynamic-path`
- **Domain:** nextjs
- **Category:** build_error
- **Verification:** ai_generated
- **Fix Rate:** 82%

## Root Cause

The generateStaticParams function is missing or incomplete, so Next.js cannot statically generate pages for dynamic routes during build time.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| next@13.4.0 | active | — | — |
| next@14.0.0 | active | — | — |
| next@14.2.10 | active | — | — |

## Workarounds

1. **Implement generateStaticParams to return an array of all possible slug values. If the data source is dynamic, use fetch or a database query.** (85% success)

2. **If the number of slugs is too large, use incremental static regeneration (ISR) by adding revalidate to the fetch or page config.** (75% success)

3. **Use dynamic rendering with `export const dynamic = 'force-dynamic'` to skip static generation entirely.** (90% success)

## Dead Ends

- **** — The page will be generated for the dummy slug but still fail for other slugs if they are accessed. (80% fail)
- **** — This will cause a 404 for any slug not pre-generated, which is not the intended fix. (90% fail)
- **** — This changes the application structure and may break existing functionality. (95% fail)
