Get a misleading error message when uploading file to data endpoint without setting a file name

[lil131]

If uploading a file to the /namespaces/{ns}/data endpoint, and the file name is "" or not set, the request will fail with a misleading error message:

{ "error": "FF10218: Error reading multi-part form input: EOF" }

Heyy @lil131 , @awrichar , can I work on this issue?

[AryanSharma9917]

Here's what I can perform

func uploadHandler(w http.ResponseWriter, r *http.Request) {

// Check if the file name is empty or not set
file, header, err := r.FormFile("file")
if err != nil {

	http.Error(w, err.Error(), http.StatusInternalServerError)
	return
}
defer file.Close()
if header.Filename == "" {
	http.Error(w, "Error: File name is empty or not set", http.StatusBadRequest)
	return
}

fmt.Fprintf(w, "File uploaded successfully!")

}
