lb4 discover unable to recognize MariaDB

Steps to reproduce

1. Create a new project using lb4 todolist-mariadb
2. Create a new datasource using lb4 datasource

mariadb.datasource.ts

import {inject, lifeCycleObserver, LifeCycleObserver} from '@loopback/core';
import {juggler} from '@loopback/repository';

const config = {
  name: 'mariadb',
  connector: 'mysql',
  url: 'mysql://node:123@localhost/todolist',
  host: 'localhost',
  port: 3306,
  user: 'node',
  password: '123',
  database: 'todolist',
};

@lifeCycleObserver('datasource')
export class MariadbDataSource
  extends juggler.DataSource
  implements LifeCycleObserver {
  static dataSourceName = 'mariadb';
  static readonly defaultConfig = config;

  constructor(
    @inject('datasources.config.mariadb', {optional: true})
    dsConfig: object = config,
  ) {
    super(dsConfig);
  }
}

3. Run lb4 discover but doesn't show any models!

$ lb4 discover
? Select the connector to discover mariadb
? Select the models which to discover (Press <space> to select, <a> to toggle all, <i> to invert selection)
$

Current Behavior

Unable to create models from MariaDB database
