Hi, After resolving the previous problem, I'm running into another (perhaps my knowledge of Javascript is not up to pair). I have a stack that reads a resource that was already created, such as:

const theQueue = aws.sqs.getQueue({
        name: "the-queue"
    });
exports.QueueArn = theQueue.arn.apply(arn => arn);

However, the const

theQueue

is empty. What I'm doing wrong? Thanks

The

aws.sqs.getQueue

function returns a

Promise<GetQueueResult>

(https://github.com/pulumi/pulumi-aws/blob/cfcf3ed0c7019484ffc2a62de4498e41d802ee71/sdk/nodejs/sqs/getQueue.ts#L12). In JavaScript, you would need to somehow rendezvous with the promise's result, as it is produced asynchronously, either using the new

await

syntax if you're on a newer Node.js or TypeScript (https://www.typescriptlang.org/docs/handbook/release-notes/typescript-1-7.html), or use the

then

function to retrieve it (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then). For instance

exports.QueueArn = theQueue.then(q => q.arn);

Note here that

QueueArn

will itself be a promise. An alternative way to accomplish this same thing is to use the static function

aws.sqs.Queue.get

, in which case the code you wrote will work almost exactly as-is:

const theQueue = aws.sqs.Queue.get("the-queue");
exports.QueueArn = theQueue.arn;

It's unfortunate there are two ways to do this same thing, however in many cases the functions offer slightly different functionality -- in this case, they are virtually identical.

Thanks. Spotted my problem. When using

then

I was trying to return the object! Cheers
