Hi, today when i start working i receive this error:

error: bundling failed: SyntaxError: Unexpected end of JSON input
at JSON.parse ()
at FileStore.get (/Users/user/Projects/project/node_modules/metro-cache/src/stores/FileStore.js:26:19)
at /Users/user/Projects/project/node_modules/metro-cache/src/Cache.js:76:40
...

It's a know error? What can i do to debug it?

react-native: 0.57.8
npm: 6.7.0
node: 10.14.1

I've come across this one a couple of times already because I keep gettings this error and I don't want to restart my computer each time (even though it works)

This way I was able to fix it
rm -rf ~/Library/Developer/Xcode/DerivedData && rm -rf ./node_modules && npm cache clean --force && yarn && react-native link && react-native run-ios

Not sure if you really need all of it but at least it does the trick for me.

I've restart my computer and this error has gone. Simple as it.

I have faced the same issue. Tried to build the apk with "gradlew clean assembleRelease" then "react-native run-android" as normally. It works
