Debugging with expo 48 on iOS device when starting expo with --tunnel option is not working

I am using a development build with expo 48 and iOS device

I started metro with
‘npx expo start --dev-client --tunnel’

pressed ‘j’ on the expo cli terminal, I see an error:
No compatible apps connected. JavaScript Debugging can only be used with the Hermes engine.

start expo using 'npx expo start --dev-client ’ and debugger can be connected.

Appreciate any ideas/pointers on how to get debugging working with --tunnel option ?
Note: when using --tunnel option, device logs are seen on the metro terminal
Pressing ‘r’ from metro terminal reloads the app on iOS device
Only debugger connection is failing with error: ‘No compatible apps connected. JavaScript Debugging can only be used with the Hermes engine.’
