ParticipantNotReadyError

Every member RPC is routed by the target member’s own call_id/node_id, not the local call’s. Those arrive with the member’s first full state event — member.joined, member.updated, or the call.joined roster. A participant first seen through a partial event such as member.talking has no call context yet, and an empty one can never address the member, so reading target throws rather than sending a doomed RPC.

Readiness never regresses: once a participant’s context has arrived, it stays.

Examples

import { ParticipantNotReadyError } from '@signalwire/js';
try {
  await participant.mute();
} catch (error) {
  if (error instanceof ParticipantNotReadyError) {
    // Seen only via member.talking so far — retry once member.joined arrives.
  }
}

setLayout validates every targeted member upfront and throws this before sending any request, leaving the layout unchanged.

• Participant.target — reading it doubles as a readiness probe.
• CallNotReadyError — the same gate for the local leg.
