Console.log doesn't work in async function

Question

I'm trying to log a statement in an async function as follows:

async generateCharts (insights) {
  const { url } = await this.reportsClient.createReport(insights)
  console.log('url from reports', url)
  return this.parse(url)
}

Log statement doesn't show up though, and I'm sure it's because of the async function. Is that correct? Anyway to work around this?

I just ran your code and it works fine. Have you tried forcing `createReport` to fulfill to verify this? — Mike Cluck, Jan 30 '17 at 17:00
FYI, `async` functions are not part of ES6 (ES2015). They *will* part of thies year's release, ES2017. — Felix Kling, Jan 30 '17 at 19:46

Note that errors are swallowed "silently" within an async function – just like inside normal Promises. Unless we add try / catch blocks around await expressions, uncaught exceptions – regardless of whether they were raised in the body of your async function or while its suspended during await – will reject the promise returned by the async function.

Your example lacks of context but, IMHO, that's because your createReport function never fulfills. There are no other reasons why the console.log would not get executed.

Same here. I had two functions with the same name. The second one took priority while I was editing the first one. – Max Mar 15 '23 at 10:02
