signature.load(x) physically works but the signature does not render


When I call the .load() method on the signature pad, the method is success as the .isEmpty() method returns false. However, the signature does not appear on the control (it does not render).

What could I be doing wrong?

When I take the base64 data produced by .getSignature() and plug it into the Preview tab of the Syncfusion demo page (https://ej2.syncfusion.com/javascript/documentation/signature/open-save/) and click "Open", it raises a 400 error visible in the developer console with no additional clues as to the cause of the error. I did this to compare what I was doing to what the SF page is doing - but it did not work. In my case, I do not get a 400 error as it is loaded in the client.

Additional information:

- this is on a password protected page so I cannot share it.

- ej2.min.js v19.4.56 (

<script type="text/javascript" src="https://cdn.syncfusion.com/ej2/dist/ej2.min.js">

- the page has a Smart Wizard control on with 5 pages, 3 of which have signature pads. All function correctly in terms of capture and save (using .getSignature()) but the .load() simply doesn't render.
