Unable to see Android logs in react-native app using adb logcat: no matches found: *:S

According to the official doc, typing adb logcat *:S ReactNative:V ReactNativeJS:V in the terminal will display all the Android Logs, however when I do so I get the following error message: no matches found: *:S. I have put Log statements in my custom native modules like so : Log.e(TAG, "Unsupported media type:" + type);.I searched for this problem online and found no solution(No one has had the same error as me, apparently).

I would like to add that the code is working fine.

Useful to debug native errors (when the app won't even start)

adb logcat "*:E"

Useful to debug JS code errors

adb logcat "*:S" ReactNative:V ReactNativeJS:V

I am assuming that you are using zsh for the terminal. Try using it like this

adb logcat '*:S' ReactNative:V ReactNativeJS:V

Hope this will help.

Try using:

adb logcat -d

-d Dump the error log on the screen Instead of using the adb logcat which displays everything on the screen,things you need and things you don't need
