Hey @jmuthalaly!

I was able to reproduce your error and fix it.

Basically your node version is too old. array.flat was introduced to node in 11.0.0 (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/flat).

Upgrading to node >= 11.0.0, should fix it!

@kevinschaich, perhaps node >= 11.0.0, should be mentioned as requirement in docs. ☺️

Cheers!
