Flutter/Dart SocketException Uploading Video File to URL

Question

I am recieving this error message when attempting to upload a video file to the speicified URL:

DioError (DioError [DioErrorType.DEFAULT]: SocketException: OS Error: Connection reset by peer, errno = 54, address = storage.googleapis.com, port = 64995)

Note: It is a DioError as I am using the dio Dart/Flutter package: https://pub.dev/packages/dio I recieve the error using equivilent API such as the http library.

Code to upload the video file selected from storage:

        //File videoFile...

        FormData data = FormData.fromMap({
          "videoFile": await MultipartFile.fromFile(videoFile.path),
        });
    
        Response response = await Dio().post(
          directUpload.url,
          data: data,
          onSendProgress: (int sent, int total) {
            print("$sent $total");
          },
        );

The URL (directUpload.url) is one generated from and provided by the Mux API to their Google Cloud Storage.

https://storage.googleapis.com/video-storage-us-east1-uploads/...

When post is called, a small amount is uploaded (e.g. 655524 / 17840042) and then the error occurs. The test video is 17.8 Mb in size.

Running this on an iOS device or the iOS simulator produces the same result/error.

I have tried: flutter clean, flutter upgrade, deleteing Podfile and pod repo update, deleting the app from device. All to no avail.

Solution 1

Change from a POST to a PUT request resolves the issue.

Solution 2

yes, I have same problem with Dio.

current can't upload data type Uint8List

My temporary solution: use http lib http: ^0.12.1

import 'package:http/http.dart' as http;

Future uploadData(Uint8List imageData) async {
    await http.put(preData.url, headers: getHeader(), body: imageData);
}

use:
List<int> imageData = File(filePath).readAsBytesSync();
await uploadData(imageData);

hope to help you
