Exporting diagram results in error: Tainted canvases may not be exported.

[Chad Carey]

I am trying to export and it was working fine but now it is telling me this when I try to export.

Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported. What would cause this?

[Chad Carey]

this seems ot have something to do with ImageElements, which is another problem I'm having (https://www.syncfusion.com/forums/146368/imageelement-doesn39t-always-show-images)

If the images are not loaded or not loading at all, export works. If the images load, even partially, the export breaks.

The image either should be hosted in an application or it should in same domain, so only the image will be exported. It is an behavior of JavaScript. Please refer to our help documentation.    Help documentation: https://ej2.syncfusion.com/aspnetmvc/documentation/diagram/shapes/?no-cache=1#image    We have created a sample in which we have rendered an layout sample. The image rendered in layout is hosted in the application.    Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/orgchartsamplemodified-2059214017
