Hi there! 👋🏼 As you're new to this repo, we'd like to suggest that you read our code of conduct as well as our contribution guidelines. Thanks a bunch for opening your first issue! 🙏

This looks like the same issue as "notifications enabled, but no services configured" (fixed by #869)

Either remove "shoutrrr" from WATCHTOWER_NOTIFICATIONS or add notification URLs to WATCHTOWER_NOTIFICATION_URL to fix it locally

To avoid important communication to get lost in a closed issues no one monitors, I'll go ahead and lock this issue. If you want to continue the discussion, please open a new issue. Thank you! 🙏🏼
