Expo debug: waiting for bundler on 127.0.0.1 getting 404 for http://127.0.0.1/json/list #235
Description
Description of the bug
When I start the debugger via "Expo: Debug Expo app on a device or simulator, using Hermes" I get an popup which tells me Expo debug: waiting for bundler on 127.0.0.1 but nothing happens. From monitoring the network traffic I see that requests are made to http://127.0.0.1/json/list which just error out with 404.
The weird thing is that the debugger was working for me a few weeks ago and also just accessing http://127.0.0.1 returns a valid response:
