Error message

SIGNUP_DISABLED

What it means

The private __check_signup reads ENABLE_SIGNUP from configuration/env (default '1'). When ENABLE_SIGNUP == '0' AND no WorkspaceMemberInvite exists for the email, AuthenticationException code 5015 (SIGNUP_DISABLED) is raised. If an invite exists, signup is allowed even with ENABLE_SIGNUP off — invites bypass the global gate.

Solutions

  1. Have a workspace admin invite the user's exact email, then retry sign-up.
  2. If self-serve sign-up should be allowed, set ENABLE_SIGNUP=1 in the instance config/env and restart.
  3. Confirm the sign-up email exactly matches the invited email (the invite lookup is case-sensitive after lowercasing).

Example fix

# before (env)
ENABLE_SIGNUP=0
# user tries to sign up uninvited -> SIGNUP_DISABLED

# after (option A: invite)
admin invites user@example.com -> user signs up with that exact email
# after (option B: open signup)
ENABLE_SIGNUP=1  # then restart the web service
Defensive patterns

Strategy: validation

Validate before calling

from django.conf import settings
import os
ENABLE_SIGNUP = os.environ.get('ENABLE_SIGNUP', '1')
if ENABLE_SIGNUP == '0' and not WorkspaceMemberInvite.objects.filter(email=email).exists():
    return bad_request('Signup disabled; ask your admin to invite you')

Try / catch

try:
    adapter._BaseAdapter__check_signup(email)
except AuthenticationException as e:
    if e.error_code == 5015:
        return bad_request('Sign-up is disabled. Request an invite.')
    raise

Prevention

When it happens

Trigger: Self-serve sign-up attempt on an instance where ENABLE_SIGNUP=0 and the user's email has not been invited to any workspace.

Common situations: Enterprise/SSO-only deployments disabling public sign-up; admin forgot to invite a user before they try to register; email mismatch between invite and sign-up attempt (case/typo).
