Transferring an empty file may close the connection prematurely

[chsxf]

Bug Description
The transfer of an empty file closes the connection prematurely.
The file Empty.twig was previously empty. By adding a commented content, the action went through. This has been reproduced many times.

I also get an error when I try uploading empty files,
most probably that's because of an integrity check after uploading files, which fails because the file is empty.

Error:

I can confirm that this is still an issue in 4.3.5. The "de.json" file below was empty and I have received this error every time. Once the file had content, the error disappeared:

uploading "img/slideshow/3.jpg"
uploading "index.html"
uploading "languages/de.json"

I'm experiencing the same error with an empty .prettierrc file.
