Error message

Multiple accounts exist for this email (different login providers)

What it means

Thrown as HTTP 400 when the invited email matches more than one user account, which happens when the same email is registered through different login providers (e.g. Google OAuth and email/password). The system can't disambiguate which account to add.

Solutions

1. Ask the user to remove or consolidate one of the duplicate accounts (delete the unused provider account)
2. As admin, merge or delete the duplicate user record in the database so only one remains
3. Invite using an email tied to a single account

const users = await lookupUsersByEmail(email);
if (users.length > 1) { askUserToPickAccountOrConsolidate(); return; }

const isUniqueAccount = (users: User[]): users is [User] => users.length === 1;

try { await addTeamMember(orgId, email); } catch (e) { if (/Multiple accounts/.test(e.message)) { showMessage('Ask member to remove duplicate login'); return; } throw e; }

When it happens

Trigger: Calling addTeamMemberByEmail for an email that exists multiple times in the users table with different provider identifiers.

Common situations: Collaborator signed up with both Google SSO and credentials; legacy duplicate accounts after provider migrations; test environments with repeated seeded signups.
