I wrote this simple code for test the jsPDF library:

const base64Img = require('base64-img');
const JsPDF     = require('jspdf');

const LAYOUT    = base64Img.base64Sync('img/layout.png');    

$('#esporta').click( () => {
    var pdf = new JsPDF();
    pdf.addImage(LAYOUT, 'PNG', 18.25, 19.25, 190, 255);
    pdf.save('test.pdf');
});

I have a simple button that when it clicked the pdf should be generated; but I have this error:

Uncaught TypeError: Cannot read property 'charAt' of undefined at new e (/Users/th3g3ntl3man/Repository/thermowell-design/node_modules/jspdf/dist/jspdf.min.js:269) at HTMLButtonElement.$.click (export.js:62) at HTMLButtonElement.dispatch (jquery-3.3.1.min.js:2) at HTMLButtonElement.y.handle (jquery-3.3.1.min.js:2)

The line export.js:62 is the creation of the pdf: var pdf = new JsPDF();

It is a reported issue. You can see here. By the time I type this message. The fix patch has not been merged yet. You can use the zip file attached here temporarily and wait for next official version released.

Extract the zip file, and copy them to node_modules/jspdf/dist, overwrite the original four files, and everything will be OK.

Today we released 1.5.3. This should fix your issue.
