pdf embed API- invalid content error

[Alon5FCD]

Hi,

This happens to me when i try to reach my viewer page in another way. the standard way with the same file works and i can't seem to find the problem. BTW, no cleanup is needed because it's the first viewed pdf.

Uncaught Error: Invalid content information is provided.

I have the same error when I call the API like this:

this.adobeDCView = new window.AdobeDC.View(config);
/* Invoke the file preview API on Adobe DC View object */
    this.adobeDCView.previewFile({
    /* Pass information on how to access the file */
    content: {
        /* Location of file where it is hosted */
        location: {
            promise: Promise.resolve(buffer) // pdf file,
...
the buffer is an ArrayBuffer for the PDF file. 
We used to use the PSPDFKit to view the PDF, like this:

PSPDFKit.load({
	document: myDocumentArrayBuffer
});
It works OK on PSPDFKit, but the same document arrayBuffer doesn't work when passed to adobeDCView. 
Any ideas?

For me, it was a timing problem.

Creating the viewer involve some asynchronous calls. I transformed some of them to async await instead of good old promises and it solved my problem but i think that your problem is a bit different.
