Hi,

yesterday my PDF Embed API stopped working properly for no reason.

If I load it more than once in the same page, without refreshing, it gives me the error 'index.js:44 Uncaught dc-core loaded twice'.

I didn't edit anything about it.

This is the code:

var pdfurl = <?php echo json_encode($pdfUrl ?? null) ?>;

var pdfname = <?php echo json_encode($pdfName ?? null) ?>;

document.addEventListener("adobe_dc_view_sdk.ready", function(){

var adobeDCView = new AdobeDC.View({clientId: ".............", divId: "adobe-dc-view"});

adobeDCView.previewFile({

content:{location: {url: pdfurl}},

metaData:{fileName: pdfname}

}, {defaultViewMode: "FIT_PAGE", showAnnotationTools: false, showLeftHandPanel: true,

dockPageControls: true});

});

</script>

This is the log:

index.js:44 Uncaught dc-core loaded twice
haRa @ index.js:44
__webpack_require__ @ bootstrap:19
EbfC @ AdobeDCViewBase.js:13
__webpack_require__ @ bootstrap:19
(anonymous) @ ViewSDKInterface.js:2
(anonymous) @ ViewSDKInterface.js:2
(anonymous) @ ViewSDKInterface.js:2

Any suggestions gratefully received.

Cheers, Daniel

I am also seeing this, I utilize the embed on an LMS, and have the core loading each time an embed is on a page, if i have subsequent pages that i move through it stops loading properly and a refresh must occur for it to display, am wondering if a variable could be set to check if the core is already loaded first before it try's a second time?

@CSumner102 You can check for window.AdobeDC.

@TylerL24 Your comment - are you ONLY talking about cases where the script tag is loaded twice? If not, please open a new thread.

@Crew31128935gi26 So do you get the error with 2 + embeds, even if you have 1 script tag?

@Raymond Camden yes i was getting the dc-core loaded twice in the console, I just edited my code to this

<script type="text/javascript">
  function initializeAdobeDCView() {
    var adobeDCView = new AdobeDC.View({clientId: "Your ID", divId: "adobe-dc-view"});
    adobeDCView.previewFile({
      content: {
        location: {url: "Your File URL"}
      },
      metaData: {fileName: "Your File Name"}
    }, {
      embedMode: "FULL_WINDOW",
      defaultViewMode: "FIT_WIDTH",
      showFullScreen: true,
      showAnnotationTools: false,
      showZoomControl: true,
      focusOnRendering: true,
      showDownloadPDF: true
    });
  }
  function loadViewerScript() {
    if (window.AdobeDC && window.AdobeDC.View) {
      initializeAdobeDCView();
    } else {
      var viewerScript = document.createElement('script');
      viewerScript.src='https://documentservices.adobe.com/view-sdk/viewer.js';
      viewerScript.onload = initializeAdobeDCView;
      document.body.appendChild(viewerScript);
    }
  }
  loadViewerScript(); // Load the Adobe DC View SDK and initialize the viewer
</script>

and now it checks to see if the core is already loaded before it try's to again.

I have been having the same issue since the 14th as well. Most of my larger PDFs with annotations do not load. I have tested it with samller image based PDF files and those have been able to load. Been attempting to troubleshoot but have not found a resolution yet.

Does the error go away if you have the script tag only once on your page? I mean the one loading the library.
