Showing attributes of models using Sequelize and Handlebars

As a novice in the world of programming, I am currently immersed in a website project where users can write and post articles. One crucial aspect I am focusing on is displaying the history of articles written by each user on their account page. Despite utilizing sequelize and handlebars for this purpose, I am encountering an issue where the user's username appears correctly but not the titles of their articles in the History Section.

Seeking solutions to address this dilemma, I have set up my controller to reference both the User and Story models to filter out stories authored by the current user. Subsequently, I employ res.render to pass these variables to my hbs page:

getAccount: async (req, res) => {
   const user = await User.findOne({where: {username: req.session.username}})
   const stories = await Story.findAll({
      where: {
         userId: user.id
      }
   })
   console.log(stories, stories.title);
   stories.forEach(story => {console.log(story.title);})
   res.render('user_account', { user, stories })
}

The structure of my HTML page utilized for rendering this information is as follows:

<div class="user-title">
    <h1>Hello {{username}} </h1>
</div>

<div class="storyList-pannel">
    <h2>History</h2>
    <div class="articles-pannel">
        {{#each stories}}
        <div class="article-title">
            <h3> {{title}} </h3>
        </div>
        {{/each}}

However, upon inspecting the console, I notice that the title is returning 'undefined'. Oddly enough, I am able to retrieve its value when iterating through it with a forEach loop, leaving me puzzled regarding the cause of this discrepancy.

To enhance the efficiency of your query, consider including the raw: true option. According to the guidance provided in the Model Querying documentation:

By default, finder methods return instances of the model class rather than plain JavaScript objects. Sequelize automatically converts database results into appropriate instance objects. If you wish to bypass this conversion and receive a raw response, include { raw: true } as an option when utilizing the finder method.

The features and limitations related to accessing prototype properties and methods of the context object in Handlebars >= v4.6.0 are extensively discussed. Leveraging a raw query output from sequelize allows your handlebars templates to seamlessly access object properties.

Implement the solution as follows:

const stories = await Story.findAll({
   where: {
      userId: user.id
   },
   raw: true 
});
