Protocols, domains, and ports must match. This happens when the pdf viewer is loaded because it tries to dispatch a custom event to the parent document: function webViewerLoad() { const config = getViewerConfiguration(); const event = document.createEvent("CustomEvent"); event.initCustomEvent("webviewerloaded", true, true, { source: window }); try { parent.document.dispatchEvent(event); } catch (ex) { console.error(`webviewerloaded: ${ex}`); document.dispatchEvent(event); } _app.PDFViewerApplication.run(config); } I have no idea why that's done, but I guess it's harmless and doesn't affect any functionality. CONSOLE MESSAGE: Feature policy 'Fullscreen' check failed for iframe with origin 'webkit-pdfjs-viewer://pdfjs' and allow attribute ''. This happens when the viewer checks is fullscreen is supported to enable the presentation mode. 1850159 1 webkit-bug-importer 2022-03-10 10:18:49 -0800 <rdar://problem/90106581> 2078586 2 raphael.stonehorse 2024-12-02 12:37:41 -0800 Any solution for this problem?
