# 🟠 addParticipants frontend sends { participants: string[] } array but backend expects { userId: string } single user
|
|
|
|
**Severity:** major
|
|
**Domain:** Chat
|
|
**Labels:** bug, frontend, major, chat

|
|
|
## Description
|
|
|
|
The frontend addParticipants action (chat.ts line 425) sends { participants: string[] } as the body. The API documents POST /api/chat/:id/participants with body { userId: string } — a single user. Backend expects a single userId, not an array. Bulk participant addition will be silently handled incorrectly.
|
|
|
|
## Current Behavior
|
|
|
|
addParticipants sends an array payload that the backend does not expect. Participant addition may fail or be ignored.
|
|
|
|
## Expected Behavior
|
|
|
|
Frontend should send { userId: string } and call the endpoint once per participant, or backend should be updated to accept an array.
