How to print out Apify requestQueue.getInfo() at run time? - output

Question

The docs on requestQueue.getInfo().
Code
function printRequestQueue(requestQueue){
let { totalRequestCount, handledRequestCount, pendingRequestCount } =
requestQueue.getInfo()
.then(()=> {
console.log('\nRequest Queue:\n total:', this);
console.log('\nRequest Queue:\n total:', totalRequestCount);
console.log(' handled:', handledRequestCount, '\n pending:', pendingRequestCount);
})
.catch( (error) => console.log(error));
}
When run in the runtime environment Apify.main(async () => { ... }, it returns undefined:
Request Queue:
total: undefined
handled: undefined
pending: undefined

Answer 1

You don't seem to be returning the contents of the response back from the operation promise and so the variables are indeed uninitialized at the time of logging them. Operation itself should be returning this result and you can confirm so by logging the result of the promise - e.g. .then(response) => {console.log(response)}:

Thanks to Vasek. I post below 2 solutions:
Solution 1
async function printRequestQueue (requestQueue){
var { totalRequestCount, handledRequestCount, pendingRequestCount } = await
requestQueue.getInfo();
console.log(`Request Queue info:` );
console.log(' - handled :', handledRequestCount);
console.log(' - pending :', pendingRequestCount);
console.log(' - total:' , totalRequestCount);
}
Solution 2
function printRequestQueue (requestQueue){
requestQueue.getInfo().then((response)=> {
console.log('total:', response.totalRequestCount);
console.log('handled:', response.handledRequestCount, '\n pending:',
response.pendingRequestCount);
console.log('\nFull response:\n', response); })
.catch( (error) => console.log(error));
}
