Push Notifications Not Working on Self-Hosted v0.7.353

Hi Team,

We are running Huly self-hosted v0.7.353 and attempting to enable browser push notifications along with Gmail-based email notifications. Push events are not being delivered, and the notification service logs do not show any activity related to receiving or sending notifications. We would like to describe our current setup and the exact issue we are experiencing.

Current Environment

Huly version: v0.7.353
Deployment method: Docker Compose (official self-host repository)
Access method: HTTPS via reverse proxy
VAPID keys: Generated using web-push generate-vapid-keys

notification:
image: hardcoreeng/notification:${HULY_VERSION}
environment:
- PORT=3335
- DB_URL=${CR_DB_URL}
- SERVER_SECRET=${SECRET}
- SECRET=${SECRET}
- QUEUE_CONFIG=redpanda:9092
- SOURCE=[example@gmail.com](mailto:example@gmail.com)
- PUSH_PUBLIC_KEY=xxxxxxx
- PUSH_PRIVATE_KEY=xxxxxxx
depends_on:

front:
PUSH_PUBLIC_KEY=xxxxxxx

transactor:
environment:

SERVER_PORT=3333
SERVER_SECRET=${SECRET}
SECRET=${SECRET}
DB_URL=${CR_DB_URL}
STORAGE_CONFIG=minio|minio?accessKey=minioadmin&secretKey=minioadmin
FRONT_URL=http://localhost:8087/
ACCOUNTS_URL=http://account:3000/
FULLTEXT_URL=http://fulltext:4700/
STATS_URL=http://stats:4900/
QUEUE_CONFIG=redpanda:9092
NOTIFICATION_URL=http://notification:3335/
What We Tested

Browser notification permission has been allowed
Service Worker is registered successfully
VAPID public key is correctly loaded in the frontend
Triggered events such as mentions, task assignments, and comments

The Problem

Push notifications are not delivered to the browser
The notification container logs do not show any activity such as:
push received
push sent
failure events
Transactor logs show normal application activity, but no attempt to send push notifications
There is no clear error message indicating why the notification service is not being triggered.

Help us enable push notification service, Thanks in advance !
