The number of members has reached the limit of your…

Error message

The number of members has reached the limit of your subscription.

What it means

HTTP 403 from `cloud_edition_billing_resource_check("members")`. Inside the decorator, when `resource == "members"` and `0 < members.limit <= members.size`, it aborts with `The number of members has reached the limit of your subscription.` Invite/add-member operations are blocked at the quota ceiling.

Solutions

  1. Upgrade the workspace plan to raise the seat limit.
  2. Remove an inactive member to free a seat before inviting a new one.
  3. Check `FeatureService.get_features(...).members` (`limit` vs `size`) in the UI and warn before the user attempts to invite.
  4. Confirm the features cache is fresh if you believe the count is wrong.

Example fix

// before
await inviteMember(email)  // 403 when at seat limit
// after
const { members } = await getFeatures()
if (members.limit > 0 && members.size >= members.limit) {
  alert('Seat limit reached — upgrade or remove a member.')
} else {
  await inviteMember(email)
}
Defensive patterns

Strategy: validation

Validate before calling

from services.feature_service import FeatureService

_, tenant_id = current_account_with_tenant()
features = FeatureService.get_features(tenant_id, exclude_vector_space=True)
m = features.members

def can_add_member() -> bool:
    return not (m.limit > 0 and m.size >= m.limit)

if not can_add_member():
    # surface upgrade / remove-member prompt instead of inviting
    ...

Type guard

def seats_available(limit: int, size: int) -> bool:
    return not (limit > 0 and size >= limit)

Try / catch

try:
    resp = client.post("/workspace/members/invite-email", ...)
except HTTPError as err:
    if err.response.status_code == 403 and "members" in err.response.text:
        # seat limit reached — upgrade or remove a member
        ...
    raise

Prevention

When it happens

Trigger: Inviting a new member (or any operation gated by `cloud_edition_billing_resource_check("members")`) on a tenant whose seat count has reached the plan's seat limit.

Common situations: Team plan with a 3-seat limit trying to add a 4th member; bulk invite pushing count over the cap; stale features cache making `size` undercount (less common).
