[Bug]: Cannot perform a multipart/form-data request without any file

[Acturus]

What happened?

Hi, I tried to make a test without sending any file to an upload route on my project and the client shows "Transaction in progress..." indefinitely and I need to click on Discard to stop it.

The request was made with a form body with multipart option enabled.

I have tried this case with other tools and in my application and the route works.

Steps to reproduce?

1. Launch the app
2. Create HTTP request with a route that receives a file
3. In body tab, select the Form option, enable Multipart switch
4. Send request

What did you expect to happen?

Show my custom error message like "No file was attached"
