error.password.space_invalid

Error message

error.password.space_invalid

What it means

CheckPassword enforces password rules; currently the only enforced rule is that the password must not contain a space character. Violating it returns the translatable code error.password.space_invalid.

Solutions

1. Remove space characters from the password and retry.
2. Sanitize/validate the password client-side before submission to give early feedback.
3. Improve UX: show the 'password cannot contain spaces' rule in the form hint.
4. If passphrase-style passwords are desired, update CheckPassword to allow spaces and adjust the i18n message.

Example fix

// before
const password = 'my secret 123';
await resetPassword(password);
// after
const password = 'my-secret-123';
await resetPassword(password);

function passwordHasSpace(pw: string): boolean { return /\s/.test(pw); }
if (passwordHasSpace(pw)) alert('Password cannot contain spaces');

try {
  await api.resetPassword(pw);
} catch (e) {
  if (e?.msg === 'error.password.space_invalid') {
    showError(t('error.password.space_invalid'));
  }
}

When it happens

Trigger: Calling CheckPassword (directly or via ResetPassword/Check flows) with a password containing a space, e.g. 'my pass123'.

Common situations: Users typing passphrases with spaces in the reset-password or change-password form; promptForPassword in CLI setup accepting any input including spaces; password managers generating passphrases with spaces.
