Hello guys! I've followed all the documentation guidelines, I've been looking for some solved issues, I've tried to correct this of many ways. **But I still can not use this lib in my application in Angular 6 with dotnet core.** When I install the lib _("jspdf": "^1.4.1")_ and try to use that, the application crashes with the error: _"... window is not defined."_. Error on debugger:  Error on browser:  My code: ``` ... import * as jsPDF from 'jspdf'; ... ngOnInit(): void { let doc = new jsPDF({ orientation: 'landscape', unit: 'in', format: [4, 2] }); doc.text('Hello world!', 1, 1); doc.save('two-by-four.pdf'); } ... ``` Thanks in advance!
