The jsPDF library is for the client side (web browser) which is why it's expecting a window variable to be present. Luckily someone has already answered how to make this work server side here. Taken from that answer:
global.window = {document: {createElementNS: () => {return {}} }};
global.navigator = {};
global.btoa = () => {};
var fs = require('fs');
var jsPDF = require('jspdf');
var doc = new jsPDF();
doc.text("Hello", 10, 10);
var data = doc.output();
fs.writeFileSync('./document.pdf', data);
delete global.window;
delete global.navigator;
delete global.btoa;
