Dropbox Community ModeratorI see, thanks for clarifying. I believe the combined serialization is expected in this case, per the Stone documentation:
Union members that are ordinary structs (
coordin the example) serialize as the struct with the addition of a.tagkey.
In this case, the UploadError union member UploadWriteFailed is a struct.
There are relatively few such cases in the API, and UploadWriteFailed (a struct inside an error union) is one of them; the others seem to be recent additions (e.g., LockConflictError inside LockFileError).
I also tripped over this error, because the author of the dropboxQt package that I use (https://github.com/osoftteam/dropboxQt) made the same mistake in their translation from Stone to C++/Qt (expecting the struct to stand as a single object embedded in the union, not broken out as fields). Sigh.
