Error message

An invalid email provided: not provided

What it means

Sentinel message produced by the auth preflight validation when the submitted email field fails validation — the schema parse or email validator reports an invalid address, and 'not provided' is the placeholder when no email was sent at all. The request is rejected with an invalid-argument style error before any account lookup happens.

Solutions

1. Provide an email address in the request body — the sign-in/sign-up call was made with an empty or missing email field.
2. Validate the email client-side (non-empty, RFC format) before submitting to avoid this round trip.

Example fix

if (!email || !/^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(email)) {
  setError('Please enter a valid email');
  return;
}
await signIn({ email });
