"Unable to resolve module" debuggerWorker errors in recent react-native releases

I keep my project(s) relatively up to date with the latest RN releases. This error seems to be coming up more and more lately.

Error: Unable to resolve module `./debugger-ui/debuggerWorker.d9da4ed7` from ``:

None of these files exist:
  * debugger-ui/debuggerWorker.d9da4ed7(.native|.native.js|.js|.native.json|.json|.native.ts|.ts|.native.tsx|.tsx)

Really makes it hard when trying to debug issues and a debugger statement does noting and errors are not reported to the browser tab where the console output goes.

I've already tried wiping node_modules. Is this a known issue with a concrete fix available?

Happens to me recently using expo and android. The solution was to clear all Expo Go data:

  • Long press the Expo go icon
  • Then select App info
  • At the bottom of the screen, press Clear Data
  • And press Clear all data
  • Relaunch expo go and the react native app

I closed the app (pressing home twice and swiping up), then started it again from the simulator and it worked.

I had to come across a similar issue after updating @react-native-community/cli-debugger-ui to 4.2.1. Tried out several methods, nothing worked. Reverting @react-native-community/cli-debugger-ui back to 3.0.0 resolved the issue for me.

Got stuck with this exact issue for hours. Just found that this occurs only on device where app is already installed with debug mode enabled.

I fixed it by:

  • uninstalling manually app from device (cmd+H to display simulator home) then long click on app icon and click on cross to delete app => this forces disabling debug mode,
  • then run app again from xcode.

Enabling debug mode after that works normally.
