Fix: No Static Path Found for Requested Path in Astro

What Causes This Error?

This error occurs when you visit a URL that matches a dynamic route pattern, but getStaticPaths() didn’t return that specific path. The route exists, but the requested path wasn’t generated.

The Problem

---
// src/pages/blog/[slug].astro
export function getStaticPaths() {
  return [
    { params: { slug: 'post-1' } },
    { params: { slug: 'post-2' } },
  ];
}
---

<!-- Visiting /blog/post-3 throws error - not in getStaticPaths -->

The Fix

Add Missing Path

---
export function getStaticPaths() {
  return [
    { params: { slug: 'post-1' } },
    { params: { slug: 'post-2' } },
    { params: { slug: 'post-3' } }, // ✅ Add the missing path
  ];
}
---

Generate Paths Dynamically

---
import { getCollection } from 'astro:content';

export async function getStaticPaths() {
  // ✅ Generate from actual content
  const posts = await getCollection('blog');
  return posts.map((post) => ({
    params: { slug: post.slug },
    props: { post },
  }));
}
---

Add Catch-All Route

---
// src/pages/blog/[...slug].astro
export function getStaticPaths() {
  const posts = await getCollection('blog');
  return [
    ...posts.map((post) => ({
      params: { slug: post.slug },
      props: { post, is404: false },
    })),
    // ✅ Catch-all for unknown paths
    {
      params: { slug: undefined },
      props: { is404: true },
    },
  ];
}

const { post, is404 } = Astro.props;
---

{is404 ? <h1>Post Not Found</h1> : <h1>{post.data.title}</h1>}

Common Scenarios

Content Was Deleted

---
// If you deleted a blog post but still have links to it
export async function getStaticPaths() {
  const posts = await getCollection('blog');

  // Check if your content collection has the expected entries
  console.log('Available posts:', posts.map(p => p.slug));

  return posts.map((post) => ({
    params: { slug: post.slug },
    props: { post },
  }));
}
---

Case Sensitivity

---
// URLs are case-sensitive!
export function getStaticPaths() {
  return [
    { params: { slug: 'my-post' } },    // Matches /blog/my-post
    // Does NOT match /blog/My-Post or /blog/MY-POST
  ];
}
---

Enable SSR for Dynamic Content

---
// src/pages/blog/[slug].astro
export const prerender = false; // ✅ Handle at runtime

const { slug } = Astro.params;
const post = await db.posts.findOne({ slug });

if (!post) {
  return Astro.redirect('/404');
}
---

Quick Checklist

• Verify the path exists in getStaticPaths() return
• Check for typos and case sensitivity
• Ensure content collection entries exist
• Consider SSR for dynamic/user-generated paths
• Add catch-all for graceful 404 handling
