PDF Embed API "An error was encountered while processing the file. Some features might not work."

I'm trying to embed a PDF on my Squarespace site using the API PDF Embed tool.

I've spent hours trying to figure this out, but no matter what I do I get this error message. It all seems to stem from the url. When I use a different url/PDF source (Google Drive, a seperate page on my website, etc.) I get another error that wants me to force reload the page. Sending the url to documentcloud.adobe.com has been the closest I've gotten to making this work, but still nothing. Any help is appreciated. 

Here's my code:

<div id="adobe-dc-view" style="height: 360px; width: 500px;"></div>
<script src="https://documentcloud.adobe.com/view-sdk/main.js"></script>
<script type="text/javascript">
document.addEventListener("adobe_dc_view_sdk.ready", function () {
var adobeDCView = new AdobeDC.View({
clientId: "e4235918972b49e4982970007f80b8bd",
divId: "adobe-dc-view"
});
adobeDCView.previewFile({
content:{ location: {url: "https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:6d5449b0-b543-494d-ad59-d39a92f4f1da"} },
metaData: { fileName: "Pop Music USA" }
}, {
embedMode: "SIZED_CONTAINER",
showDownloadPDF: false,
showPrintPDF: false
});
});
</script>
