Cannot read properties of undefined (reading 'appendChild') at o.createNotificationPopup

[Gilbert Dimaano]

I always get this error every time I load the PDF in the PDF viewer for the first time in my browser.

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'appendChild')
at o.createNotificationPopup (pdf-editor-DzDyRoS7.js:350:119750)
at o.openNotificationPopup (pdf-editor-DzDyRoS7.js:350:120905)
at o.onControlError (pdf-editor-DzDyRoS7.js:350:290027)
at o.createAjaxRequest (pdf-editor-DzDyRoS7.js:350:116919)
at pdf-editor-DzDyRoS7.js:350:107203

The error seems to be coming from this line.

o.prototype.createNotificationPopup = function(e) {

        var t = this;

        if (!this.isMessageBoxOpen) {

            var A = O("div", {

                id: this.pdfViewer.element.id + "_notify",

                className: "e-pv-notification-popup"

            });

            !d(this.pdfViewer.pageOrganizer) && this.pdfViewer.pageOrganizer.dialogDivElement ? this.pdfViewer.pageOrganizer.dialogDivElement.appendChild(A) : this.viewerContainer.appendChild(A),

The error is trigged when loading a document to the viewer.
viewer.load('document.pdf', '')

Here is a sample setup of my pdf viewer

Hi Gilbert Dimaano,

Thank you for the update. This issue typically occurs when a PDF document is loaded before the necessary resources in the PDF Viewer are fully initialized. To resolve this, we recommend loading the PDF document within the resourcesLoaded event using the load API.

 

We’ve attached the UG for how to use the resourcesLoaded event to properly load the PDF document. Please review the UG and check if it resolves the issue. If you have any questions or need further assistance, feel free to reach out.
