cropper.zoom(0.1) gives Uncaught TypeError

[ThorVestaberg]

I have this in my aspx page, and the cropper.setAspectRatio work fine, but I get an error when I try to set a default zoom.

ERROR:
Uncaught TypeError: Cannot read properties of undefined (reading 'width')
at Cropper.zoom (cropper.js:2403:37)

CODE:

<script src="js/cropper.js"></script> <script src="js/main.js"></script>

           <script type="text/javascript">
               cropper.setAspectRatio(16 / 9);                   
               cropper.zoom(0.1);
           </script>

The zoom method must be called AFTER the ready event is fired, see the first paragraph of the methods documentation.
