kendoPDFViewer Errhas been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Hi Kendo Team,

I am getting this error when trying to open a pdf from Azure Blob using kendoPDFViewer. (Error: has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.)

I use token-based authentication by SSL token included to the image/pdf URLs and It works fine for image viewing using kendoImageEditor.

My code is simple as follows:

                            this.viewer = $("#pdfViewer").kendoPDFViewer({

                                pdfjsProcessing: {

                                    file: pdfUrl,

                                },

                                width: "100%",

                            }).data("kendoPDFViewer");

 

Could you please let me know how to fix this issue?

Or do I need to use dplProcessing with an Authorization token
