no_more_seat

Error message

No more seat available in the Space ${spaceId}.

What it means

Produced during inviteByEmail's locked processing loop for non-team workspaces: seat math (quota.memberCount + successfulCandidates.length + 1 > quota.memberLimit) shows adding this candidate would exceed the plan's member limit. The candidate is skipped and NoMoreSeat is written to its InviteResult.error. Code no_more_seat, HTTP 400 semantics; note the running successfulCandidates count means earlier candidates in the same batch may have consumed the last seats.

Solutions

1. Check the workspace member quota (memberLimit - memberCount) before inviting and cap the batch accordingly.
2. Free seats by removing inactive members, or upgrade the workspace plan / apply a license to raise memberLimit.
3. Read results[i].error.name === 'no_more_seat' per row and prompt the owner to upgrade instead of retrying — retrying cannot succeed.

Example fix

// before
await inviteByEmail(ws.id, 10_emails); // 3 seats left -> later rows: no_more_seat

// after
const { memberCount, memberLimit } = await getWorkspaceSeatQuota(ws.id);
const free = memberLimit - memberCount;
if (emails.length > free) {
  await confirm(`Only ${free} seats left — invite first ${free} and upgrade?`);
}
await inviteByEmail(ws.id, emails.slice(0, free));

// pre-check seat availability before a non-team invite batch
const { memberCount, memberLimit } = await getWorkspaceSeatQuota(workspaceId);
const freeSeats = memberLimit - memberCount;
const sendable = emails.slice(0, Math.max(0, freeSeats));
if (emails.length > sendable.length) promptUpgradeFor(emails.length - sendable.length);

function isNoMoreSeatResult(x: unknown): boolean {
  const err = (x as { error?: unknown })?.error ?? x; // works for per-item results and thrown errors
  return String((err as { name?: string }).name ?? '').toLowerCase() === 'no_more_seat';
}

const results = await inviteByEmail(workspaceId, emails);
for (const r of results) {
  if (isNoMoreSeatResult(r)) { showUpgradePrompt(); break; } // retrying cannot help
}

When it happens

Trigger: Inviting N emails to a free/pro (non-team) workspace that has fewer than N free seats; a batch where the first emails fill the remaining seats and later ones hit this error per-item.

Common situations: Hitting the member limit of a free plan mid-onboarding; inviting a large list without checking the member quota first; seat count drifting from the UI because pending invites also count toward memberCount.
