Same issue here..

const fileExtension = coverImage.split(".").pop();

  // Create a new FormData instance
  const formData = new FormData();

  formData.append("image", {
    uri: coverImage,
    name: "image-" + new Date() + `.${fileExtension}`,
    type: `image/${fileExtension}`,
  } as any);

  // Append other form fields to FormData
  formData.append("food_name", data.food_name);
  formData.append("description", data.description);
  formData.append("price", String(data.price));
  formData.append("category", data.category);
  formData.append("addOn", JSON.stringify(data.addon));

  // Append sizes if applicable
  if (isSize && data.size.length > 0) {
    data.size.forEach((input, index) => {
      formData.append(`size[${index}]`, input.size);
      formData.append(`size_price[${index}]`, String(input.price));
    });
  }

  const response = await axios.post(
    `${app_url}/addMenuItem/${resId}`,
    formData,
    {
      headers: {
        "Content-Type": "multipart/form-data",
      },
    }
  );

When I console.log req.file and req.body,

undefined [Object: null prototype] {
food_name: '',
description: '',
price: 'null',
category: '',
addOn: '{"addon":"","price":0}'
}

Here I'm not sending any data in req.body only sending file to req.file which I get undefined..
This works fine with react native 0.73.x but not with 0.74.x
