Body in form mode, Empty file input cause request to fail

[IGLOU-EU]

V: 4.11.0

If I make a request with an empty input, there is an error.
It does say If I make a request with an empty input, there is an error, but in the case I'm currently dealing with I would have wanted my multipart to be sent with the empty input.
The error message displayed when the request is executed is not relevant, and it is not immediately clear what the problem is.

By the way, thank you very much for this cool "add-on" :)
