After doing research in internet I found that the issue is something related to prop-types but not sure what I have to do to fix this issue. I am using prop types version "prop-types": "^15.6.0".
I am able to resolve the issue. Since I upgraded to react v15 to v16 the issue was with react-alert module as I was using react-alert v1. So upgrading it to react-alert v4 resolved issue for me.
