//index.js

    const { email, description, files } = form;
    const formData = new FormData();
    Array.from(files).forEach((file) => {
        formData.append(file.name, file);

   }

   dispatch(uploadChallengeThunk(formData));

//service.js

  Array.from(formData).forEach((item) => {
    console.log("
