no_more_seat

Error message

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

What it means

Thrown inside inviteMembers (non-team workspace) when admitting one more seat would exceed the workspace seat quota: quota.memberCount + already-successful-this-batch + 1 > quota.memberLimit. Team workspaces skip this (they go through allocating-seat path); non-team workspaces enforce the cap per candidate. Reported as no_more_seat (bad_request, HTTP 400).

Solutions

1. Upgrade the workspace plan / increase memberLimit to fit the new seats.
2. Reduce the batch size to the remaining available seats (memberLimit - memberCount).
3. Remove unused/pending members to free seats before inviting.
4. Refresh quota.getWorkspaceSeatQuota in the UI before enabling invite.

Example fix

// before
inviteMembers(workspaceId, manyEmails); // exceeds seats
// after
const free = quota.memberLimit - quota.memberCount;
inviteMembers(workspaceId, manyEmails.slice(0, Math.max(0, free)));

const quota = await getWorkspaceSeatQuota(workspaceId);
const free = Math.max(0, quota.memberLimit - quota.memberCount);
const toInvite = emails.slice(0, free);
if (toInvite.length === 0) throw new Error('No seats available; upgrade plan to invite more');
await inviteMembers(workspaceId, toInvite);

function hasFreeSeats(quota: { memberCount: number; memberLimit: number }): boolean {
  return quota.memberCount < quota.memberLimit;
}

When it happens

Trigger: Inviting to a non-team workspace when the number of members plus pending invites in this batch would exceed memberLimit.

Common situations: Plan limit reached and the user tries to invite more; a batch where earlier candidates consumed the last seats; stale quota shown in the UI that no longer reflects reality.
