libraw errors with DNG files processed by Adobe LightRoom

Hi team,
I have a couple of DNG files that were created in Adobe LightRoom. You can find them here:

https://drive.google.com/drive/folders/1mxxENtJ6P51ksR6choAGbUSud451lNJX...

They fail when calling unpack() with the error "Corrupted data or unexpected EOF". Call to open_file works. Hence raw-identify is able to parse metadata from the file.

I do not have the Adobe DNG APIs as part of my libraw build. Do I need these OR are these files expected to work out of the box with libraw alone?

Regards,
Dinesh
