amplify-js: Custom auth lambda trigger is not configured for the user pool.

Describe the bug

Using the Vue.js <amplify-sign-in> component, when attempting to log in with a blank password, I get the error “Custom auth lambda trigger is not configured for the user pool.”

To Reproduce Steps to reproduce the behavior:

Configure a Cognito user pool with just the email attribute required, and the OAuth 2.0 Authorization code grant flow. Scopes set to 'email', 'profile', 'openid'.

Expected behavior

An error message like “password is required”. Ideally, the form wouldn’t even submit.

What is Configured?

Manual configuration:

const config = {
  Auth: {
    region: 'us-east-1',
    userPoolId: 'us-east-1_xxxxx', 
    userPoolWebClientId: 'xxxxxxxxxxxx',
    oauth: {
      scope: ['email', 'profile', 'openid'],
      redirectSignIn: 'http://localhost:8080',
      redirectSignOut: 'http://localhost:8080',
      responseType: 'code',
    },
  },
  Storage: {
    AWSS3: {
      bucket: 'xxxxxxxx',
      region: 'us-east-1',
    },
  },
};

export default config;

Hi, we have been aware of this issue and have this in our milestone. Currently, i guess this happens on sign-in component’s when there is no password. Right? There are password less sign in that disrupts the flow we have. I will keep you updated on this ticket as we progress.

one simple hack to it is telling the cognito that passwordless login is not permitted…we do it by going to aws cognito console’s app client and Enable username password based authentication (ALLOW_USER_PASSWORD_AUTH) which by default is not enabled…also we can set it in amplify.configure

For anyone interested, I was able to customize the error message like this:
import { I18n } from 'aws-amplify';

I18n.putVocabularies({
    fr: {
      'Custom auth lambda trigger is not configured for the user pool.': 'Veuillez renseigner le mot de passe',
    },
});
I wish this could be constants instead of strings, like for other translations in the new UI components version, but still a workaround. It still sends the request though, but at least displays a corresponding error.

managed to replace the text by

I18n.putVocabularies({
  en: {
    'Custom auth lambda trigger is not configured for the user pool.': 'Password cannot be empty',
  },
});
