Sharing is not configured on this deployment

Error message

Sharing is not configured on this deployment

What it means

HTTP 500 from the share-enable endpoint (share.py:126). Share links are built from settings.config.frontend_base_url; when it is empty the server refuses to enable sharing rather than mint URLs pointing at localhost (which would only resolve on the backend host). The code logs 'frontend_base_url is not configured; refusing to enable share' and returns 500 — a deliberate deployment-misconfiguration tripwire fired at share-enable time.

Solutions

1. Set FRONTEND_BASE_URL (e.g. https://app.example.com) in the backend environment/.env and restart the backend.
2. Verify with a follow-up request — once set, share tokens resolve to correct public URLs.
3. Deployment checklists: include frontend_base_url in environment validation so misconfigs surface at boot, not at share time.
4. Client-side: on 500 with this detail, surface 'sharing unavailable on this deployment' instead of a generic error.

Example fix

# before
# backend/.env missing the var -> share enable returns 500

# after
FRONTEND_BASE_URL=https://app.example.com

// before enabling shares, confirm the deployment exposes a public frontend URL
const cfg = await getDeploymentConfig();
if (!cfg.frontend_base_url) {
  showNotice('Sharing is unavailable on this deployment');
} else {
  await post(`/chat/sessions/${id}/share/enable`);
}

function sharingConfigured(frontendBaseUrl: string | undefined | null): boolean {
  return typeof frontendBaseUrl === 'string' && frontendBaseUrl.length > 0;
}

try { await post(`/chat/sessions/${id}/share/enable`); } catch (e) { if (e.status === 500 && /not configured/.test(e.detail)) { showSharingUnavailable(); return; } throw e; }

When it happens

Trigger: Enabling chat sharing on a deployment where FRONTEND_BASE_URL is unset/empty in backend settings — common in fresh local setups, misconfigured staging, or backend-only containers.

Common situations: New environment brought up without FRONTEND_BASE_URL in .env; docker-compose service missing the variable; renaming domains and forgetting the backend copy of the setting.
