async.forever error in 2.3.0

See original GitHub issue

What version of async are you using? 2.3.0 Which environment did the issue occur in (Node version/browser version) NodeJs >= 7.6 What did you do? Please include a minimal reproducable case illustrating issue. I have a function that works for async 2.1.5

_async.forever(async function(next) {
  try {
    // do something
  } catch (err) {

What did you expect to happen? This function should run the async callback function forever…I am using NodeJs >= 7.6 so async is supported natively… What was the actual result? After upgrading to 2.3.0, now I get this error TypeError: next is not a function

Perhaps we should make it more clear in the docs that a final callback isn’t passed to an async function.

Thanks for the response. I did figure out the throw way to break the forever loop. Although, I used throw ("true") & then checked if error. message === "true" in my catch block.

Maybe throw ( false ) won’t need error. message verification. Will try later.

Also, regarding your break solution, that is what I tried first, but node gave error: Invalid break statement & so I used forever in the first place.

Anyways, thanks again for the response. Using throw does work as a workaround to the next callback.
