Also, please update the demo, It's medals[i], not medal[i]. As well as my problem where the asynchronous call (ngio.callComponent) was slower than the for loop. Here's my corrected code:

    if (ngio.user) {
        console.log('Get', medal_name, 'ID...');
        for (var i = 0; i < medals.length; i++) {
            medal = medals[i];

            /* look for a matching medal name */
            if (medal.name == medal_name) {
                console.log('Medal Found!', medal_name, '=', medal.id);
                break;
            }
        }
        
        if (medal === null) {
            console.log('No Medal found');
            return;
        }

        /* we can skip unlocking a medal that's already been earned */
        if (!medal.unlocked) {
            console.log('Unlock', medal.name);
            /* unlock the medal from the server */
            ngio.callComponent('Medal.unlock', {id:medal.id});
        } else {
            console.log('Have medal:', medal);
        }
    } else {
         console.log('Error@ngio.getValidSession')
    }

The issue might be related to this, too.
