it looks like the issue here is that websocket failed to build during npm install.

I see

└ [email protected] (git://github.com/frozeman/WebSocket-Node.git#6c72925e3f8aaaea8dc8450f97627e85263999f2)

the websocket module does have a native code component that needs to compile with node-gyp:

> [email protected] install ~/web3c/node_modules/websocket
> (node-gyp rebuild 2> builderror.log) || (exit 0)

  CXX(target) Release/obj.target/validation/src/validation.o

Do you see errors there?

My issue got resolved when I installed new version of web3

@willscott see issue https://github.com/ethereum/web3.js/issues/2863#issuecomment-503624214 and associated commit https://github.com/ethereum/web3.js/commit/b27eff44920d4776b07c19db7f42ec518796ee46 for the fix. Upgrading the following web3 dependency to v1.0.0-beta.52 or higher should resolve this issue. https://github.com/oasislabs/web3c.js/blob/542571404fcb2ce23a0fe01109106bcd207c1a6d/package.json#L51
