Hi @fantasy525 and thanks for reaching us. Is it https://github.com/fantasy525/fantasy-music project? Is it ready to be used by us to reproduce your problem? Do you have any instructions for us to how get started with it?

[fantasy525]

@ruslan-bikkinin Yes ,you can clone it ,then just do this:
1.yarn install
2. react-native run-android

[fantasy525]

@ruslan-bikkinin I'm not sure which line of code is going to happen ,but I have met many times.and you can also see this issues

[fantasy525]

@ruslan-bikkinin I type 'debugger' in my file,but finally the breakpoint stops in other file

other file:

and I've given up on the red breakpoint.I want to type 'debugger' manually.but Why is my debugging experience so bad? Today red breakpoint is still incorrect and sometimes program still can't stop at breakpoint...

[fantasy525]

@ruslan-bikkinin Hi,I think it is possible that the cache of the previous code caused the breakpoint to be placed incorrectly.just a guess...,I hope you can solve the problem as soon as possible, thank you!

I have the same problem

Hi @fantasy525 , I tried to debug your application with Chrome debugger on Windows and Linux and it looks like there are some problems with source maps inside React Native. As you can see at this GIF I was able to reproduce the problem in Chrome Debugger without using VS Code at all. I would recommend you to create an issue in React Native repo and describe your situation there, also add a link to this issue and attach this GIF there as well. Feel free to re-open if you have any updates in the future.
