Solutions

1. Refresh the organization member list and skip the invite if present
2. Disable the invite button while the request is in flight and after success
3. Treat this error as a no-op success in idempotent invite flows

Example fix

// before
await addTeamMember(orgId, email);
// after
const members = await listMembers(orgId);
if (!members.some((m) => m.email === email)) {
  await addTeamMember(orgId, email);
}

const members = await listMembers(orgId);
if (members.some((m) => m.userId === user.id)) return; // already member

const isAlreadyMember = (orgs: {id: string}[], orgId: string): boolean => orgs.some((o) => o.id === orgId);

try { await addTeamMember(orgId, email); } catch (e) { if (/already a member/.test(e.message)) return { added: true }; throw e; }

When it happens

Trigger: Re-sending an invite for a user who already accepted; user already belongs via a previous invite; UI state stale so the member list doesn't show them.

Common situations: Invitee clicked the invite twice; org list not refreshed after adding; frontend allows repeated submits (double-click, retry); user was added programmatically elsewhere.
