Completes an upload made with UploadFile and stores it as the new content of the file; returns
only the data file version.

## Remarks

**For M-Files components only.** M-Files Server calls it on another M-Files Server to forward
[UploadFileCommit](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCObjectOperations/UploadFileCommit/index.md). Applications should call
`UploadFileCommit`.
- Changes the file content of the object. The checks are those of `UploadFileCommit`: the object
  must be checked out to the caller, and the caller needs edit access to it.
- Unlike `UploadFileCommit`, it does not fill in unset file times and returns no object version
  information.
- Requires a vault session of a login that has a user account in the vault.
