Question 1

How to update or bump the mini_racer dependency in Huginn for better compatibility?

Accepted Answer

The mini_racer dependency is being updated via Pull Request #3539. Track that PR for the new version. As a workaround, you can manually point to a newer mini_racer release in your Gemfile if needed.

Question 2

How to fix Huginn Docker container on Unraid when web UI is not accessible due to MySQL permission denied or data directory errors?

Accepted Answer

There are two common issues: 1) Permission denied: run `chown -R 1001:0 /mnt/user/appdata/your-huginn-mysql-folder` on the Unraid host to allow the container's MySQL user (uid 1001) to write. 2) MySQL data directory already has files, causing 'Aborting': clear the directory with `rm -rf /path/to/mysql/volume/*` (ensure backup if needed) and restart the container. Check logs for exact errors.

Question 3

Why does my Huginn WebsiteAgent stop creating events after a few days when using 'on_change' mode?

Accepted Answer

The 'on_change' mode may fail to detect changes if the page content has slight variations (e.g., dynamic ads, timestamps) or if the event key is not unique. Workaround: Switch mode to 'all' and use a DeDuplicationAgent to filter out duplicates, or set expected_update_period_in_days to a lower value (e.g., '1') to force frequent re-scraping.

Question 4

How to send only the 'message' field from a JSON payload via the Email Agent in Huginn?

Accepted Answer

Use a Formatting Agent or EventFormattingAgent before the Email Agent to extract the desired field. Set the formatting agent's `instructions` to: `{ "body": "{{message}}" }`. Then configure the Email Agent's `body` as `{{body}}`. Alternatively, try setting the Email Agent's `body` directly to `{{message}}` without the nested path `{{message.message}}`, as Liquid templates resolve top-level keys.
