## Remarks

`logical_size` must equal the number of bytes uploaded. Otherwise the call fails with "File size
mismatch." (0x8004003D) and the server **removes the upload**, so it must be uploaded again.
Commit only once: a second commit of the same upload also fails with "File size mismatch." and
removes it. The response is empty; the upload is used by its `upload_id`.
