flipper: Plugin Hermes Debugger (RN) is unavailable

For me, the Hermes debugger is only available when I press Cmd + D on the Virtual device and choose Open Debugger, but it switches to a device called React Native with no application selected, and that device not support other plugins such as Network, Advanced Async Storage, Redux Debugger,… This is weird.

This is still happening in v0.241.0. Reverting to v0.237.0 works in the meantime.

Same for me with Flipper Version 0.239.0 (50.0.0) iPhone 13 Pro Max with iOS 17.1.2 Hermes for RN 0.72.7

I faced similar issue while working on android emulator before updating flipper it is working fine

🐛 Bug Report

The debugger in Flipper has stopped working for us after upgrading Flipper to v0.238.0. The Hermes Debugger (RN) plugin is now under Unavailable plugins whereas it used to be under React Native out of the box.

It says Device plugin 'Hermes Debugger (RN)' is not supported by the selected device

The behavior is the same for both iPhone and Android simulators.

If I downgrade Flipper to v0.237.0 the Hermes debugger starts working again immediately.

To Reproduce

1. Start your native app
2. Start Flipper
3. Look for Hermes Debugger plugin

Environment

• iPhone 14 Pro Max simulator, iOS 17.0.1
• Android Pixel 3a API 32 emulator, Android version 12
• emulators run on macOS 14.1.2

Same issue on 0.239.0. Any link to download flipper 0.237.0 for mac?

@johnbaishya You can download platform specific Flipper file from here - https://github.com/facebook/flipper/releases/tag/v0.237.0 I can confirm the Hermes Debugger (RN) works on v0.237.0 but doesn’t work on anything after that.

This is still happening in v0.241.0. Reverting to v0.237.0 works in the meantime.

For now i did this as temporary

Using an android emulator API 33 with RE:Pack and react native (webpack server), I’m seeing the same thing. No Hermes debugger available. This was both on 0.237.0 and latest. Anyone find a way to get that working?
