Release / release (push) Successful in 58s
Telegram webhook handler crashed with sqlalchemy.exc.MissingGreenlet
when processing any incoming message after committing the chat row:
TelegramChat.bot_id == bot.id
^^^^^^
MissingGreenlet: greenlet_spawn has not been called
AsyncSession expires all instances on commit. Accessing bot.id/bot.token
after that triggers implicit lazy-load I/O from a sync attribute getter,
which can't enter the greenlet dispatcher → crash.
Fix: snapshot bot.id + bot.token to locals before commit, refresh the
ORM instance after a successful commit so handle_command() can still
use it, and route the remaining call sites through the snapshot
variables.
Notify Bridge
A generic bridge between service providers and notification targets.
Notify Bridge monitors services (like Immich photo servers) for changes and dispatches notifications to configurable targets (Telegram, webhooks) using customizable templates.
Architecture
- Service Providers — Connectors to external services (Immich, more coming)
- Trackers — Monitor specific collections within a provider for changes
- Tracking Configs — Define what events to watch for and scheduling rules
- Notification Targets — Where to send notifications (Telegram chats, webhook URLs)
- Template Configs — Jinja2 templates that format notifications per provider type
Project Structure
packages/
core/ — Shared library: providers, models, notifications, templates
server/ — FastAPI REST server with SQLite database
frontend/ — SvelteKit dashboard (Svelte 5, Tailwind CSS v4)
Quick Docker Deploy
docker run -d \
--name notify-bridge \
--restart unless-stopped \

-v notify-bridge-data:/data \
-e NOTIFY_BRIDGE_SECRET_KEY=$(openssl rand -hex 32) \
git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge:latest
Then open http://localhost:8420 in your browser.
