When I run react-native start, I am getting the following message
Error: A non-recoverable condition has triggered. Watchman needs your help! The trigg
You can solve it by trying one of the below solutions:
first pass hit line of code in your terminal and test it :
echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_watches && echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_queued_events && echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_instances && watchman shutdown-server
or try to use "react-native run-android" or "run-ios" in the root of your project and then (in other terminal) "react-native start"
otherwise perhaps the debugger page was left open from previous sessions. Closing the tab completely and then opening the debugger in a new tab solved the issue.
if none of the above solution doesn't work with you try to restart your PC
