Cannot perform DCAPI command if DCAPI is disabled

[Robert5DE7]

Just trying to get started with the basics:

I copied the 'Copy it Run it' code into our application.

var adobeDCView = new AdobeDC.View({ clientId: "OUR CLIENT ID", divId: "adobe-dc-view" });
adobeDCView.previewFile({
 content: {location: {url: "https://documentcloud.adobe.com/view-sdk-demo/PDFs/Bodea Brochure.pdf"}},
 metaData: {fileName: "Bodea Brochure.pdf"}
});

When it runs the spinner shows 'Opening Document 100%' but it throws an error a Promise rejection 'Cannot perform DCAPI command if DCAPI is disabled'.

If I click through all the Promise rejections the pdf does eventually display, though any mouse move over the pdf generates more Promise rejections.

I must be missing something obvious???

I also tried using our own pdf with the url pointing at our AWS location, the spinner shows 'Opening Document 0%' then the promise rejection, the pdf never loads

Haven't been able to resolve the promise rejection but our pdf is now rendering I think it just renders very slow in the viewer.

In Chrome native all 6 pages render almost instantly, in PDFJS  it renders in a few seconds but in the Adobe viewer it is taking minutes and several pages are incorrectly or partially rendered.

The partial rendering seems to just be a question of timing, wait long enough and it seems to sort itself out.
It also seems this maybe more of an issue with the inline mode.
