Detox iOS failing to start intermittently on React Native 0.68.2

See original GitHub issue

What happened?

About 50% of the time Detox iOS fails with the following error:

15:18:10.143 detox[7891] WARN:  [DetoxConnection.js/ERROR, #50663] Action dispatched too early, there is no session to use:

HINT: Please report this issue on our GitHub tracker:
https://github.com/wix/Detox/issues

{
  params: [Object],
  type: 'AppWillTerminateWithError',
  messageId: -10000
}

What was the expected behaviour?

Expect Detox to consistently start on iOS 15.5 and React Native 0.68.2

Was it tested on latest Detox?

I have tested this issue on the latest Detox release and it still reproduces.

Did your test throw out a timeout?

I have followed the instructions under Identifying which synchronization mechanism causes us to wait too much.

Help us reproduce this issue!

Problem seems to be related to React Native 0.68.2

In what environment did this happen?

Detox version: 19.7.1 (latest) React Native version: 0.68.2 Node version: v14.x Device model: 15.5 Simulator iOS version: 15.5 macOS version: macOS Monterey Xcode version: 12.3.1 Test-runner (select one): jest-circus

+1 to above. “detox”: “19.9.1” “react-native”: “0.68.2”

Running locally on macOS Monterey.

Interestingly enough, it works on a real Android device. but fails on the emulator (also works fine on iOS)

The issue relates to iOS failures, not Android, and you say that you have no problems on iOS. I suggest opening a separate issue with your error since I’m afraid it will disappear in this issue context. @wadey1

Yeah judging by the responses it looks like this never got fixed. I was curious when you responded how it was possible this got resolved in 19.8.x because when I looked at your PRs for react native 68 they had no actual changes to the logic of Detox. What those PRs did was upgrade your example app but they did not change Detox. @d4vidi @asafkorem
