Error message

Unable to create account because the licensed seats limit was exceeded

What it means

Raised by SeatsLimitExceeded in _create_new_account when AccountService.create_account_and_tenant raises SeatsLimitExceededError. This is a licensing/billing control: the Dify edition enforces a maximum number of seated accounts per tenant/workspace, and new account creation is refused once the cap is hit.

Solutions

Upgrade the license/plan to raise the seat cap, or remove inactive member accounts to free seats.
Check the billing/license admin page to see current seat usage versus the limit.
If seats should be available, verify the license file/env is current and the seat-count job is not stale.
Invite the user as a member of an existing workspace instead of creating a new account/tenant.

Example fix

// before: every signup creates a new tenant
register(...);
// after: when seats are full, offer invite link
if (res.code === 'limit_exceeded') showUpgradeOrInviteUI();

Defensive patterns

Strategy: try-catch

Try / catch

try {
  await register({ token, ... });
} catch (e) {
  if (e.code === 'limit_exceeded') showUpgradeOrInviteUI();
  else throw e;
}

Prevention

Monitor seat usage vs license cap before users hit the wall.
Remove inactive members to free seats before onboarding.
Keep the license file/env current; alert when seats approach the cap.

When it happens

Trigger: POST /console/api/email-register succeeds through all token checks, then create_account_and_tenant attempts to provision a tenant seat and the configured seat limit is reached.

Common situations: Self-hosted EE with a license seat cap exhausted; SaaS workspace on a plan whose seat quota is full; trial license expired or downgraded; orphaned inactive accounts still counting toward the limit.
