Significant-Gravitas/AutoGPT · warning · NotFoundError

Agent {username}/{agent_name} not found

Error message

Agent {username}/{agent_name} not found

What it means

NotFoundError raised by get_store_agent_details when no row in the StoreAgent view matches the creator username + slug pair. The StoreAgent view only contains APPROVED public listings, so absence can mean the agent doesn't exist, was renamed, was unlisted, or is still pending review.

Solutions

Verify the exact current username and slug on the store page (slugs are case-sensitive).
If the submission is pending, use the admin/preview endpoint (get_store_agent_details_as_admin path) rather than the public route.
If the listing was intentionally removed, retire the links pointing at it (redirects or 410 handling).
Search the store by name to find the listing's new slug after a rename.

Example fix

# before
await get_store_agent_details("old-username", "my-agent")
# after — resolve current creator/slug first
listing = await search_store_agents("my agent");
await get_store_agent_details(listing.creator_username, listing.slug)

Defensive patterns

Strategy: type-guard

Validate before calling

// Resolve listing by search first when details matter
const hit = await searchStoreAgents(`${username}/${agent_name}`);
if (!hit.items.length) throw new NotFoundError('no such agent');

Type guard

// Server-side shape to distinguish not-found from DB failure
function isNotFound(e: unknown): e is NotFoundError {
  return e instanceof Error && e.message.startsWith('Agent ') && e.message.endsWith(' not found');
}

Try / catch

try { return await getStoreAgentDetails(u, slug); }
catch (e) {
  if (e instanceof NotFoundError) return null; // render 'not available' page
  throw e; // DatabaseError needs attention
}

Prevention

Treat 404 as an expected state: render an 'agent unavailable' page, not an error.
Use current creator_username + slug from the store search, not cached URLs.
For pending submissions use the preview/admin route, never the public one.

When it happens

Trigger: GET public store agent details for {username}/{agent_name} where the slug is misspelled, the listing was removed/soft-deleted, the creator changed their username, or the submission is not yet APPROVED (pending/rejected versions are invisible to this query).

Common situations: Stale links/Bookmarks to agents that were unpublished; frontend routing by slug after a rename; creators previewing their own pending submission via the public endpoint instead of the admin/preview route; scrapers hitting old URLs.
