upload mp4 with expo in react native problem - react-native

Question

I'm new in react native and this might be a silly question, but when I'm trying to upload .mp4 with react native using expo in my backend server side (laravel) I receive a jpg/jpeg file which is weird because with the same code when I try to upload .mov file it works as expected without any problem.
is there anything I've done wrong?
p.s: I've already tried to fetch method and axios but I get the same result with both.
here's my code:
postForm = () => {
var body = new FormData();
body.append("title", this.state.text);
body.append("description", this.state.description);
body.append("category_id", this.state.category_id);
body.append("type", this.state.type);
body.append('media_path', {
uri: this.state.photos.photos[0].file,
name: `media.mp4`,
type: this.state.format
});
this.state.photos.photos.map((item, index) => {
console.log("addable item is", index, item.file);
//skip first photo to media_path
if (index == 0) {
console.log("avalin index: ", item.file)
return
}
else {
file = item.file.toLowerCase();
console.log("full name is", file);
let addable = {
uri: item.file,
name: `addables`,
type: this.state.format
}
body.append("addables[]", addable)
}
})
console.log("final body: ", body);
this.setState({
uploading: true,
}, function () {
let apiUrl = `${config.BASE_URL}api/products`;
console.log(apiUrl);
axios({
method: 'POST',
url: apiUrl,
data: body,
headers: {
Accept: 'application/json',
'Content-Type': 'multipart/form-data',
"authorization": this.state.token
}
})
.then((response) => {
//handle success
console.log("success response: ", response);
if (response.data.status == true) {
this.setState({
uploading: false
}, function () {
this.props.navigation.push('profile');
})
}
else {
this.setState({
uploading: false
}, function () {
this.showToast("unsuccessful operation.", "danger", 3000);
})
}
})
.catch(function (response) {
//handle error
console.log(response);
alert("response)
});
})
}
and this is what laravel logs tels me:
array (
'title' => 'test',
'description' => 'test',
'category_id' => '3',
'type' => 'video',
'media_path' =>
Illuminate\Http\UploadedFile::__set_state(array(
'test' => false,
'originalName' => 'media.mp4',
'mimeType' => 'image/jpeg',
'error' => 0,
'hashName' => NULL,
)),
)
