TypeError: Functions are not supported

I have tried to run this code as mention in docs but getting error
const { parse } = require('esprima');
const { evaluate } = require('eval-estree-expression');
const ast = parse('[1, 2, 3].map(n => n * x);').body[0].expression;

// evaluate synchronously
console.log(evaluate.sync(ast)); // => [2, 4, 6]

// or asynchronously
console.log(await evaluate(ast)); // => [2, 4, 6]
