how to store docx files to cloudinary with multer

i am trying to upload docx file to cloudinary with multer-storage-cloudinary.

here is the code i use

const storage = new CloudinaryStorage({
    cloudinary,
    params: async (req, file) => ({
        folder: 'client-documents',
        resource_type: 'raw',
        allowed_formats: ['jpg', 'jpeg', 'png', 'pdf', 'doc', 'docx'],
        public_id: `${Date.now()}`
    })
});

const upload = multer({
    storage,
    limits: { fileSize: 10 * 1024 * 1024 } // 10 MB limit
});

but when try with postman i get error

{
    "status": "error",
    "error": {
        "message": "An unknown file format not allowed",
        "name": "Error",
        "http_code": 400,
        "storageErrors": [],
        "statusCode": 500,
        "status": "error"
    },
    "message": "An unknown file format not allowed"
}
