previously there was no problem when I made new native react and run it
but now when I make new native react and run it, an error occurs
as follows

even though I didn't add any script at all,
after I created "react-native init nameAplication" I immediately ran the application I created earlier, "react-native run-android",
before it went smoothly
I run the application on my device directly
please instructions
Thank god you recreated the issue, the same thing is happening to me
but if I enable "debug JS Remotely", the application runs smoothly

Indeed, just confirmed this info in my app
Maybe if you disable delta it'll work
EDIT: Nop, it doesn't
I don't turn off delta, but it's still the same error
are there any other instructions?
please give me a clue, how is the solution to this problem
Im having the same problem
Goodluck!
that way it works, but it results in weak automatic load if run on my device
Anyone knows how to solve without the "Debug JS Remote" option?
Using the Debug JS Remotely option didn't work for me, nor did adding a polyfill for object.getOwnPropertyDescriptors
Im having the same problem
I had the same problem when I try to create a new react-native project. But this error did not happen in my previous projects.
same on Windows 10 + NodeJs 11.7
Debug JS Remotely doesn' work too
If you are working with real device, maybe adb reverse works https://facebook.github.io/react-native/docs/running-on-device
