Getting an empty array of files on the server?

Question

Node.js

I take files from the client and put them in FormData, after which I send them to the server, but on the server I get an empty

photos.ts array:

export const config = {
    api: {
        bodyParser: true
    }
}

const storage = multer.diskStorage({
    destination:(req, file, cb) => {
        cb(null, "public/uploads/photos")
    },
    filename:(req, file, cb) => {
        cb(null, file.fieldname + "-" + Date.now() + path.extname(file.originalname))
    }
})

const uploadImages = multer({ storage, limits: { fieldSize: 25 * 1024 * 1024 } });
const uploadPhotos = uploadImages.any("photos");

handler.use(uploadPhotos);

export default handler.post(async(req:any, res:NextApiResponse) => {
    try {
        console.log(req.files) // []
        res.status(200).json({ success: true });
    } catch(e) {
        console.log(e);
        res.status(500).json({
            success: false, message: "Ошибка сервера"
        })
    }
})

react input handler:

const addPhotosHandler = async(event) => {
        if (!event.target.files?.length) return;
        const formData = new FormData();

        for (let i = 0; i < event.target.files.length; i++) {
            formData.append("photos", event.target.files[i]);
        }

        const response = axios.post(`${process.env.API_URL}/api/upload/photos`, formData, {
            headers: {
                'Content-Type': 'multipart/form-data'
            }
        })
        
        response.then((res:any) => {
            setActive(false);
            console.log(res.data); // { success: true }
        }).catch(err => {
            setInfo({
                type: "error",
                text: `Ошибка сервера: ${err.message}`
            })
        })
    }
