Salesforce - Annotations

Technical Support WebViewer
1

I’m trying to expand on the sample LWC that is provided by adding a simple freeText annotation to the file.

However, I get the following error when I’m trying to do this:

Viewer is on a different domain, the promise from WebViewer function is rejected and API functions will not work because of cross domain permissions. See http://r.pdftron.com/kb_cross_origin for more information.

I’m not sure how to resolve it…could it be a Canvas issue on the Salesforce side, or something else?

Would you be able to send your code sample on how you are doing it?

initUI() {
var url = myfilesUrl + ‘/word.docx’;
var viewerElement = this.template.querySelector(‘div’);
let _this = this;

var webViewer = new PDFTron.WebViewer({
path: libUrl,
config: myfilesUrl + ‘/config.js’
}, viewerElement);

viewerElement.addEventListener(‘ready’, () => {
console.log(‘Ready event listener’);

_this.iframeWindow = viewerElement.querySelector(‘iframe’).contentWindow;

console.log(‘Attempting to post message’);

_this.iframeWindow.postMessage({type: ‘LOAD_WEBVIEWER’, file: url}, ‘*’);

console.log(‘Exiting Ready event listener’);

});

The goal is to customize the WebViewer, add annotations, loadDocument, etc after the ready event via the config.js file.

But, before I can even get to the receiveMessage function inside config.js, I’m given the following error:

Viewer is on a different domain, the promise from WebViewer function is rejected and API functions will not work because of cross domain permissions. See http://r.pdftron.com/kb_cross_origin for more information.

Hi
I apologies for the delay, I tried your code, but I was not able to reproduce it. Would you be able to share the screenshot of the network tabs from browser dev tools?
