Axios send strange array to React - reactjs

Question

I geting the data back from my API in React from a post request and I get just the first object of the entire Array.prototype
My API for the upload:
router.post("/uploads", upload.any(), async (req, res) => {
try {
if (!req.files) {
res.send({
status: false,
message: "No file uploaded",
});
} else {
let data = req.files;
res.send({
status: true,
message: "Files are uploaded",
data: data,
});
}
} catch (error) {
res.status(500).send(err);
}
});
POSTMAN gives me back:
{
"status": true,
"message": "Files are uploaded",
"data": [
{
"fieldname": "uploads\n",
"originalname": "46335256.jpg",
"encoding": "7bit",
"mimetype": "image/jpeg",
"destination": "client/uploads/",
"filename": "46335256-2020-08-04.jpg",
"path": "client/uploads/46335256-2020-08-04.jpg",
"size": 19379
},
{
"fieldname": "uploads\n",
"originalname": "120360358.jpg",
"encoding": "7bit",
"mimetype": "image/jpeg",
"destination": "client/uploads/",
"filename": "120360358-2020-08-04.jpg",
"path": "client/uploads/120360358-2020-08-04.jpg",
"size": 78075
}
]
}
perfect!
this is my function in React to upload
const uploadFiles = () => {
uploadModalRef.current.style.display = "block"
uploadRef.current.innerHTML = "File(s) Uploading..."
for (let i = 0; i < validFiles.length; i++) {
const formData = new FormData()
formData.append("images", validFiles[i])
axios
.post("http://localhost:5000/api/db/uploads", formData, {
onUploadProgress: progressEvent => {
const uploadPercentage = Math.floor(
(progressEvent.loaded / progressEvent.total) * 100
)
...// code for graphic upload
},
})
.then(resp => {
console.log(resp.data.data)
resp.data.data.map(item => {
console.log(item)
})
})
.catch(() => {
... // code
}
}
and with this I get (from the console):
[{…}]
0:
destination: "client/uploads/"
encoding: "7bit"
fieldname: "images"
filename: "46335256-2020-08-04.jpg"
mimetype: "image/jpeg"
originalname: "46335256.jpg"
path: "client/uploads/46335256-2020-08-04.jpg"
size: 19379
__proto__: Object
length: 1
__proto__: Array(0)
is an array(if I map it works) but with just the first object.
How is it possible ??
I tried even with async/await but nothing changes
Where I'm mistaking?
Thanks!
