Can you please help identify the incompatible format part? Thanks

The zero here is definitely not on place! If this is not some copy/paste mistake, you may have some trouble in your system that you have to debug. In all cases, you may print responses headers out and post here 'x-dropbox-request-id' header. This will let additional error tracing.

The path's format is all right. There should be something "behind the scene" though, as I said. By the way to see everything follow my directions exactly - the output, you posted, does NOT come from pseudo server since incomplete!
Good luck.
