React Native UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'url' of undefined at WebSocketServer

My react native app is ejected from expo. I have upgraded my react native app from expo 35 to expo 36. After upgrading I am facing two issues.

1. After build app crashes with white screen on first time open by android studio, but when i click app on simulator it starts working fine.

2. After app open I am getting error in my console

   UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'url' of undefined at WebSocketServer

I have looked for everything but didn't get any success. The error is coming in web socket server inside metro package of react native 0.61

Thanks in advance
