Handlebars: Access has been denied to resolve the Property "title" because it is not an "Own Property" of its Parent

Question

I’m having a problem with displaying mysql data by handlebars:

Executing (default): SELECT `id`, `titulo`, `conteudo`, `createdAt`, `updatedAt` FROM `postagens` AS `postagens`;
Handlebars: Access has been denied to resolve the property "titulo" because it is not an "own property" of its parent.
You can add a runtime option to disable the check or this warning:

Answer 1

In the handlebars engine settings, try using the option runtimeOptions with the properties allowProtoPropertiesByDefault and allowProtoMethodsByDefault worthwhile true.

Staying that way:

    app.engine('handlebars', handlebars({
        defaultLayout: 'main',
        runtimeOptions: {
            allowProtoPropertiesByDefault: true,
            allowProtoMethodsByDefault: true,
        },
    }))

Answer 2

app.engine('handlebars', handlebars({
        defaultLayout: 'main',
        runtimeOptions: {
            allowProtoPropertiesByDefault: true,
            allowProtoMethodsByDefault: true,
        },
}))

app.get('/pagamento', function (req, res) {
    Kitten.findAll().then(pagamentos => {
        res.render('pagamento', {
            pagamentos: pagamentos.map(pagamento => pagamento.toJSON())
        })
    })
});

Adapt your code in this example above.
