unknown member: {member_id}

Error message

unknown member: {member_id}

What it means

Thrown by agent_teams assign_task when an owner_member_id is supplied that matches no member row in that team (checked via list_agent_team_members). It compares against member IDs — the generated row identifiers returned by creation, not the human-readable member names. Passing a member name, an id from another team, or a stale id after membership changes produces this error; the task insert is aborted.

Solutions

1. Fetch the team via agent_team_get and read each member's id field; use that exact id as owner_member_id
2. Omit owner_member_id to create an unassigned task and let members claim it
3. Regenerate any stored member ids after re-creating a team

Example fix

// before
{"team_id":"team-3f9a...","owner_member_id":"researcher",...} // -> unknown member: researcher
// after: agent_team_get shows member id "m-8c21..."
{"team_id":"team-3f9a...","owner_member_id":"m-8c21...",...}

// Resolve owner to a real member id before assigning:
let view = tool_exec("agent_team_get", json!({"team_id": tid})).await?;
let owner_id = view.members.iter().find(|m| m.name == owner_name)
    .ok_or_else(|| anyhow!("no member named {owner_name}"))?.id.clone();
tool_exec("agent_team_assign_task", json!({"team_id": tid, "owner_member_id": owner_id, /* ... */})).await

fn member_id_in_team(view: &TeamView, member_id: &str) -> bool {
    view.members.iter().any(|m| m.id == member_id)
}

match tool_exec("agent_team_assign_task", args).await {
    Err(e) if e.to_string().contains("unknown member") => {
        let view = tool_exec("agent_team_get", json!({"team_id": args["team_id"]})).await?;
        // map name->id from view.members and re-submit, or drop owner_member_id (unassigned task)
        unimplemented!()
    }
    other => other,
}

When it happens

Trigger: Setting owner_member_id to the member's name ('researcher') instead of its id ('m-...'); mixing ids across teams; a member removed/re-created so the old id no longer resolves.

Common situations: LLM filling owner from the roster it wrote in the prompt (names) rather than the create response (ids); maintaining task templates that hard-code old member ids.
