locals not accessible within partials

My setup looks something like the following:

var hbs = handlebars.create({
    extname: '.hbs'
});

app.locals['static-server'] = 'https://' + config.services.assets.hostname;

app.set('views', app.path('views'));
app.engine('hbs', hbs.engine);
app.set('view engine', 'hbs');

The static-server local works properly within views, but whenever it is used within a partial, the variable is always undefined. Is this a bug, or do I have something configured incorrectly?

While in a for each loop, {{@root.yourLocalsDataKey}} may help

Confirming I experienced the same issue, unable to access a {{user}} (res.locals.user) inside an {{#each array as |item|}}

@WeiGrand 's solution worked for. {{@root.user.name}}
