Your file does not contain a preview.

Hey, I know this is an old issue but I'm not too familiar with RAWs and I'm also an OpenCamera user with the same issue.

Does this mean that DNG files embed previews, and this app only extracts the preview from DNG files with previews, instead of generating thumbnails?

Yes. This app only extracts the embedded preview. Actually generating previews reliably across different cameras and setups requires a lot more work to get good results.
