Watchman service is timing out waiting for a synchronization cookie file to be observed by the watcher within 20000 milliseconds

[ArindamRayMukherjee]

My react-native/metro/watchman setup is not syncing changes to my JS code for the app.

Versions MacOS(Ventura 13.0) react-native(0.72) iOS simulator/metro(0.76.7) watchman(2023.08.07.00)

Symptoms

1) I run the app using react-native run-ios

2) Sometimes when the app comes up I see warnings like these(some other times I don't)

warning: Watchman `watch-project` returned a warning: Recrawled this watch 23 times, most recently because:
MustScanSubDirs UserDroppedTo resolve, please review the information on
https://facebook.github.io/watchman/docs/troubleshooting.html#recrawl
To clear this warning, run:
`watchman watch-del '/Users/arindamray/IdeaProjects/temp/DanceAppCopy' ; watchman watch-project '/Users/arindamray/IdeaProjects/temp/DanceAppCopy'`

3) In watchman logs I see the following appear every minute or so

4) On making a JS change to the app code - a) Pressing R on the metro terminal, most of the times the new changes are not reflected b) If I do not press R, on some occasions after about 30 seconds of making the change something starts to wake up and I see "Refreshing..." on the iOS simulator. Once that get's done, it seems metro is running two versions of the code(old and new), I see console log statements from both versions of the ocde. If now I press R on metro the new code starts to run. c) At times b above just does not happen and metro just keeps running the old code.

What could I be doing to fix/diagnose this?

I have the same issue on linux.

Having a similar issue. Seemed to just randomly start happening. I tried restarting watchman no luck..

React Native - 0.72.6 Metro - 0.76.8 Watchman - 2023.09.18.00

Seeing this in my terminal where i run metro. Could it be from metro being on different version than RN, not sure if thats a thing?

  Usually this happens when watchman isn't running. Create an empty `.watchmanconfig` file in your project's root folder or initialize a git or hg repository in your project.
  Error: Watchman error: watchman::QueryExecError: query failed: synchronization failed: syncToNow: timed out waiting for cookie file to be observed by watcher within 60000 milliseconds: Operation timed out. Make sure watchman is running for this project. See https://facebook.github.io/watchman/docs/troubleshooting.
