Solution 1:[1]
Found out this to be a problem with node v14.x and ganache-cli v6.12.2 (ganache-core: 2.13.2).
Installing node v13.9.0 solved the issue for me.
Solution 2:[2]
in my case, reinstalling ganache-cli fixed it for me.
Solution 3:[3]
Install the latest version 7.0.3 of ganache instead ganache-cli
npm install --save-dev ganache
in code just use
const ganache = require('ganache');
const web3 = new Web3(ganache.provider());
