    Welcome to SO, check content of file:`C:\Tmp\nodejs\npm-cache\_logs\2019-01-24T04_08_31_288Z-debug.log` and add that too in question – dkb Jan 24 '19 at 04:49
  • @dkb I added debug.log in my question.Do you have any suggestions? – Chamath Naveen Jan 24 '19 at 05:12
  • are you running `npm start` from powershell? if not please do that – dkb Jan 24 '19 at 05:18
  • check solutions posted here: https://stackoverflow.com/q/42308879/2987755 – dkb Jan 24 '19 at 05:19
  • @dkb any of the above solutions didn't work for me but when i run my client application and server application separately it worked properly. Only the error occur when run both client and server application using one command 'npm run dev'. – Chamath Naveen Jan 24 '19 at 16:39
