Error message

The result of this StaticQuery could not be fetched.

This is likely a bug in Gatsby and if refreshing the page does not fix it, please open an issue in https://github.com/gatsbyjs/gatsby/issues

What it means

`useStaticQuery` looked up its query hash in `StaticQueryContext` and found no entry with `.data`. The hash should have been injected at build time by the query extractor; a miss means the runtime context and the build-time extracted data diverged. The message itself labels this a likely Gatsby bug.

Solutions

Stop the dev/build process and delete `.cache` and `public`, then re-run.
Verify all Gatsby packages share one version (`npm ls @gatsbyjs/reach-router` / `gatsby` etc.).
Trigger a hard refresh in the browser to rule out a stale client bundle.
If it persists, capture the query and open an issue at the URL in the message.

Defensive patterns

Strategy: retry

Try / catch

// In app code you generally cannot catch this usefully (it throws during render).
// Treat it as a build/CI signal: detect non-zero exit from `gatsby build` and
// clear `.cache`/`public` before retrying.
try {
  await runBuild()
} catch (e) {
  if (/StaticQuery could not be fetched/.test(String(e))) {
  await fs.rm(".cache", { recursive: true, force: true })
  await fs.rm("public", { recursive: true, force: true })
  throw e
  }
  throw e
}

Prevention

Add a clean-cache step to CI on every build.
Pin all Gatsby packages to one version to avoid context/data format drift.
Avoid killing builds with SIGKILL; let them shut down so cache writes finish.

When it happens

Trigger: Running after a build/extract that failed to register the static query; the component's compiled hash differs from what is in `page-data`/`app-data`; SSR or dev-server stale state serving mismatched data.

Common situations: Leftover `.cache`/`public` after a Gatsby upgrade; switching branches with different queries without clearing cache; a failed partial build; HMR desync in develop.
