Flutter : InternalError , Filter error, bad data when upload image on server - http

Question

I do simple upload image to server using http packages. But the problem is , when i upload it i got error Unhandled Exception: InternalError: 'Filter error, bad data'.
Upload
Future testUpload(File selfieImage, String pembertang) async {
final result = await reusableRequestServer.requestServer(() async {
//create multipart request for POST or PATCH method
var request = http.MultipartRequest('POST', Uri.parse('$baseApiUtang/addUtang'));
//add text fields
request.fields['pembertang'] = '$pembertang';
//create multipart using filepath, string or bytes
var pic = await http.MultipartFile.fromPath('selfie', selfieImage.path);
//add multipart to request
request.files.add(pic);
var response = await request.send();
//Get the response from the server
var responseData = await response.stream.toBytes();
var responseString = String.fromCharCodes(responseData);
print('responseData : $responseData');
print('responseString : $responseString');
return responseString;
});
return result;
}
With this strange problem , i try it with postman but it's work like i want.
My opinion, it's not problem in my backend code. I missed something ?
Update
Similiar problem with me on this issue
Update 2
When i look inside the code and print variable 1 by 1, i got status code 403

Hi can you pls try following code
var stream = new http.ByteStream(Stream.castFrom(imageFile.openRead()));
// get file length
var length = await imageFile.length();
// create multipart request
var request = new http.MultipartRequest("POST", uri);
var name = firstname +"."+imageFile.path.split(".").last;
// multipart that takes file
var multipartFile = new http.MultipartFile('profile', stream, length,
filename: basename(name));
In my case my can not take so much long name so i customise image name and then tried and its working .
so you can also try this.
