Steps To Reproduce

1. With RN 0.61.1, I started getting messages like these in "Output" window in VS Code when I run "Debug iOS":

The project runs fine though.

Describe what you expected to happen:

No such messages

Does this repro for you on a new project when running react-native init?

The AccessibilityInfo files are .ios.js and .android.js. I'm curious if something in your metro config isn't searching those file extensions since the error message seems to only be checking AccessibilityInfo(.native|.native.js|.js|.native.json|.json|.native.ts|.ts|.native.tsx|.tsx).

I'm curious if this is a problem in react-native that would be demonstrated in a new project or something that is specific to your project config

[StasD]

Yes, happens for a brand new project (e.g. react-native init MyCoolApp) too.

[rvgroup]

I have the same error and debug mode (in VS Code - Windows) does not work (after upgrade to RN 0.61.1)

[lucianomlima]

Happens with me too with a working 0.59.9 RN app.

The Map file failed to load when a try to connect a chrome debugger inside VScode when i launch 'attach to packager' command.

If i try with debugger inside the Chrome navigator, i can debug without any problems.
It worked fine before i migrate from RN 0.60.4

Me also having same issue if anyone having solutions..?

[Wilson-Lim]

I Am having the same problem, now i cant debug on visual studio Code

[StasD]

Guys at https://github.com/microsoft/vscode-react-native fixed this. Closing this issue.

[elicwhite]

Cool! Can you link to where they discuss and have the fix?

[grean]

You have to install the last version of vscode-react-native extension and restart vscode. The last version is 0.12.1 actually.
