handshakeexception handshake error in client (os error wrong_version_number tls_record cc 242) Flutter app/Node 服务器

Question

我正在运行的应用程序（商店应用程序）上收到 handshakeexception handshake error in client (os error wrong_version_number tls_record cc 242) error whenever making an http request( I also tried https ) but from only one ( Cyclist app ) of the two Flutter apps that connect to Node.js server. I'm using the same IP address and port on both, the Android tablet on which I'm testing both apps and for my machine. I checked Manifest Android/src/main/AndroidManifest.xml to see if I was using android:usesCleartextTraffic="true"` 但我没有..

我还可以检查什么以了解是什么导致了 Cyclist 应用程序中的错误？

这是请求：

Map<String, String> headers = {
      'Content-Type': 'application/json',
      'api_key': Environment.dbApiKey
    };

    // final Uri uri = Uri.https(Environment.dbUrl, '/api/routes');
    final Uri uri = Uri.http(Environment.dbUrl, '/api/routes');
    await post(uri, headers: headers, body: jsonEncode(route.toMap()))
.then((resp) {
      print(
          'RouteMongoRepository.saveRoute response status code is: ${resp
              .statusCode}, \n response is : ${jsonDecode(resp.body)}');
      UserRoute saved = UserRoute.fromMap(jsonDecode(resp.body)['data']);
      print('saved route to Mongo is : ${saved.toMap().toString()}');

    })  .catchError((e) => print('RouteMongoRepository.saveRoute error: $e')) ;
