This share no longer exists (gist deleted?).

Error message

This share no longer exists (gist deleted?).

What it means

This error comes from the browser-side share-loader embedded in exported HTML. After sharing, the page fetches the GitHub Gist that holds the sealed session payload; GitHub returning 404 means the gist is gone (deleted, or made inaccessible), so the shared page cannot unseal its data and throws this message to the viewer.

Solutions

  1. Re-share the session: regenerate the HTML and re-run /share to create a fresh gist, then distribute the new page.
  2. Check the gist id in the page/network tab against gist.github.com to confirm it's really gone.
  3. If you're the author, restore via GitHub's gist history/deleted-item recovery is not available — create a new gist.
  4. Keep the original session and export pipeline so shares can be regenerated on demand.

Example fix

// before: viewing a stale page — nothing to fix client-side
// after: regenerate and re-share
// omp: /share  → produces new HTML + fresh gist; distribute the new file
Defensive patterns

Strategy: try-catch

Validate before calling

// viewer-side check before relying on a share
const id = gistIdFromShareUrl;
const res = await fetch(`https://api.github.com/gists/${id}`, { method: "HEAD" });
if (res.status === 404) console.warn("This share's gist is gone; ask for a re-share");

Type guard

null

Try / catch

try {
  const blob = await fetchGistBlob(id);
} catch (err) {
  if (err instanceof Error && err.message.includes("no longer exists")) {
    showShareExpiredNotice(); // prompt author to re-run /share
  } else throw err;
}

Prevention

When it happens

Trigger: Opening a previously generated shared-session HTML page whose gist id no longer resolves: gist was deleted by the author, GitHub removed it, or the id embedded in the page is wrong.

Common situations: Author deleted the gist after sharing (or bulk-deleted gists); GitHub account deleted; DMCA/abuse takedown; sharing a page generated before the gist upload actually completed; tampered/mistyped share URL.
