Invalid regular expression and TypeError: cb.apply is not a function

[kanna998]

1. After cloning the project, while run the command "yarn start". Getting the below error, error Invalid regular expression: /(.\fixtures\.|node_modules[\]react[\]dist[\].|website\node_modules\.|heapCapture\bundle.js|.\tests\.)$/: Unterminated character class. Run CLI with --verbose flag for more details. error Command failed with exit code 1. File: uPort\uport-mobile\node_modules\metro-config\src\defaults\blacklist.js

2. After correcting the above issue by modifying the regex, run command "yarn start" now we should not get any error Then run command "react-native run-android". Once application start running in android emulator, after some seconds getting the below error

   DELTA [android, dev] ./index.js ░░░░░░░░░░░░░░░░ 0.0% (0/1)C:\Users\\AndroidStudioProjects\uPort\uport-mobile\node_modules\graceful-fs\polyfills.js:285 if (cb) cb.apply(this, arguments) ^

5. react-native run-android
