Error: Data passed to getter must include an id property (it's how we memoize) but got undefined at window.WWebJS.getContactModel.

Environment

• WAHA version: WAHA PLUS
• Engine: WWebJS
• WhatsApp account: personal
• Deployment: Docker

Description

When calling GET /api/contacts/all, the endpoint returns HTTP 500 with the following error:

Error: Data passed to getter must include an id property
(it's how we memoize) but got undefined
at window.WWebJS.getContactModel

This happens consistently whenever I try to fetch all contacts from a registered session.

Steps to Reproduce

1. Register and connect a WhatsApp session successfully
2. Call GET /api/{session}/contacts/all
3. Observe the 500 Internal Server Error response

Expected Behavior

Return a list of all contacts from the connected WhatsApp account.

Actual Behavior

The API crashes with the error above. It seems the WWebJS engine
encounters a contact with a malformed or missing id property
(possibly a corrupted/legacy contact in the phone's address book),
and instead of skipping it, the whole call fails.

Possible Cause

The getContactModel function in whatsapp-web.js requires an id
field for memoization. When iterating over all contacts, if any single
contact has an undefined or malformed ID, the entire request throws
and returns 500.

Workaround / Request

Could WAHA (or the underlying WWebJS layer) catch this error per-contact
and skip malformed entries instead of failing the entire request?
A try/catch around individual contact processing would prevent the full
endpoint from crashing.
