Estoy tratando de obtener dataURL de Salesforce ContentVerison usando canvas.toDataURL en el método LWC pero recibo el siguiente error de política CORS: " imagen de error "

Código html de LWC:

 <template> <div id="full-screen-image" class="full-screen-image"> <img data-id="prev-image" src="/sfc/servlet.shepherd/version/renditionDownload?rendition=ORIGINAL_Png&amp;versionId=06821000001Gsm8AAC&amp;operationContext=CHATTER&amp;contentId=05T21000004x5ga" class="testImage"> <canvas id="myCanvas" class="slds-hide" data-id="prev-canvas" style="border:1px solid #d3d3d3;"></canvas> </div> </template>

codigo js

 handleRotateRight() { var image = this.template.querySelector('[data-id="prev-image"]'); var canvas = this.template.querySelector('[data-id="prev-canvas"]'); var context = canvas.getContext('2d'); let img = new Image(); img.crossOrigin = "anonymous"; img.src = image.src; img.onload = function() { canvas.width = img.width; canvas.height = img.height; context.translate(canvas.width / 2,canvas.height / 2); context.rotate(Math.PI/2); context.drawImage(img, -img.width / 2, -img.height / 2); //convert to png image as dataURL var dataURL = canvas.toDataURL("image/png"); console.log('dataURL-->', dataURL); //convert that as base64 encoding var convertedDataURI = dataURL.replace(/^data:image\/(png|jpg);base64,/, ""); console.log('convertedDataURI-->', convertedDataURI); } }
