If you look at the default implementation of scripts at JavaScript it looks for javascript explicitely. Make a copy of that file, change it to match your needs, and supply as your script handler to engine:

const Scripts = require('./scripts.js');
const engine = new Engine({ scripts: new Scripts() });

However，if I change this format to "Javascript", it works.

Yes, thats what the regexp pattern is matching.
