Development Shack Technology Understood

While attempting to add an A record to my hosted zone, I kept getting this error (using the node.js SDK).

InvalidInput: Invalid request

Here was a snippet of my code:

var change = {
    Action: "UPSERT",
    ResourceRecordSet: {
        Name: "test.developmentshack.com",
        Type: "A",
        ResourceRecords: [ { Value: ipAddress }]
    }
};

route53.changeResourceRecordSets({
    HostedZoneId: zone.Id,
    ChangeBatch: {
        Changes: [ change ]
    }
}, function (error, data) {
    if (error) { throw error; }
    console.log('Pointed ' + fullDomain + ' to ' + ipAddress);
});

It turns out that the TTL is required when modifying an A record.

var change = {
    Action: "UPSERT",
    ResourceRecordSet: {
        Name: "test.developmentshack.com",
        Type: "A",
        TTL: 600,
        ResourceRecords: [ { Value: ipAddress }]
    }
};

route53.changeResourceRecordSets({
    HostedZoneId: zone.Id,
    ChangeBatch: {
        Changes: [ change ]
    }
}, function (error, data) {
    if (error) { throw error; }
    console.log('Pointed ' + fullDomain + ' to ' + ipAddress);
});
