loader.js infura transaction call js issue

[anotherrohit]

I get the following error trying to use the infura calljs. What loader am i missing? I do not see any such import on the file? Where can I get the Demo.json from? Do I have to point the path to the file to get rid of the error?
const fs = require("fs");
const { abi } = JSON.parse(fs.readFileSync("Demo.json"));

\demo-eth-tx-master>node infura-transaction/call.js
internal/modules/cjs/loader.js:582
throw err;
^
