cc @JakobJingleheimer, perhaps this could be related to #44710?

[merceyz]

Possibly the same issue as #47566

[GeoffreyBooth]

@nodejs/loaders

[JakobJingleheimer]

Yes, I think so. Antoine noted that these are all related to async messaging (warnings etc), which are known to be flaky after #44710.

We're going to remove the deprecation warnings (and their tests) for old hooks as they were deprecated multiple major versions ago (I wanna say v16 line); that will eliminate some of the flakiness.

We'll need to add specific handling for anything else that needs to communicate/coordinate with the main thread (such as writing to stdout).

[GeoffreyBooth]

Is this still an issue after the recent PRs that have landed?

[aduh95]

According to nodejs/reliability#545, no flaky ESM test have been reported since 3 days ago 🥳
