DioError [DioErrorType.response]: Http status error [500] #1171

DhavalRKansara · 2021-05-26T07:44:53Z

With Dio 4.0.0 I am getting the below error with post request and the same post request working fine with the postman.

Code:

    Map<String, dynamic> headers = <String, dynamic>{};

    if (_token != null && _token.isNotEmpty) {
      headers['Authorization'] = 'Bearer $_token';
    }

    var dio = Dio(BaseOptions(
      baseUrl: 'https://myurl.com/' + '/api',
      connectTimeout: 50000,
      receiveTimeout: 50000,
      contentType: 'application/json',
      headers: headers,
    ));
    dio.interceptors.add(LogInterceptor(
        requestBody: logEnabled(),
        responseBody: logEnabled(),
        request: logEnabled(),
        requestHeader: logEnabled(),
        responseHeader: logEnabled()));

Error:

Hi, @DhavalRKansara Did you call any print exception.toString() method in catch body?

Unfortunately, I have the same issue.
Whereas I am also using the same post method for registration it is working perfectly.
How it is possible?
Does anyone have any idea?

How did you solved it?

I expect error to be handled when catching it in try/catch block, but for some reason it is not as I'm getting error:

When I update dio to 4.0.0, some post requests response 500 error and some works fine.

I solved the error by passing {} to data parameters.

before dio 4.0.0:

var dio = Dio();
var data = {'city-id': '371000000000'};
var response = await dio.post(url1, data: null, options: Options(headers: data));

dio 4.0.0:

var dio = Dio();
var data = {'city-id': '371000000000'};
var response = await dio.post(url1, data: {}, options: Options(headers: data));

i find my issue due to vpn havent work

jinseokoh · 2021-10-01T10:34:10Z

I've experienced the same error. After looking at the server side error logs, I've found out that some of request headers from Dio was missing like content-type, token, etc. Somehow Dio seemed to have a problem in dispatching request while it fetches data from interceptors.

A quick and dirty solution I came up with was wrapping the request logic in a Future.delayed() as follows. In my case context.read<SomeCubit>().load() initiates API calls.

goes from

  @override
  void initState() {
    super.initState();
    context.read<SomeCubit>().load();
  }

to

  @override
  void initState() {
    super.initState();
    Future.delayed(const Duration(milliseconds: 300), () {
      context.read<SomeCubit>().load();
    });
  }

a7md0 · 2021-11-12T14:37:24Z

Same issue here, whenever my API is returning 4xx errors (e.g., 401) I receive this uncaught exception (even though I have the call in try/catch block)

Exception has occurred.
DioError (DioError [DioErrorType.response]: Http status error [401]
#0      DioMixin.assureDioError (package:dio/src/dio_mixin.dart:821:20)
#1      DioMixin._dispatchRequest (package:dio/src/dio_mixin.dart:678:13)
<asynchronous suspension>
#2      DioMixin.fetch.<anonymous closure>.<anonymous closure> (package:dio/src/dio_mixin.dart)
<asynchronous suspension>
)

While debugging, if I skipped this uncaught exception it continue to my catch block which is weird

dio version 4.0.1

Getting same issue 4.0.6 as well, why errors are not getting caught in try catch?

davidvalari · 2022-10-05T12:20:41Z

I found something. If you have an interceptor onError handler, it seems to be all falling back there so we basically can't catch it within the call. Removing the global onError handler solves it for me

kuhnroyal · 2023-12-07T14:25:08Z

@Shvet 500 is a server error, dio does not create that error our of nowhere. Maybe some default header is missing that is automatically added by postman. Create a reproducible sample and open a new issue.

Use

dio.interceptors.add(InterceptorsWrapper(onError: (DioError e, handler) {
return handler.reject(e);
}));

Then ,You can catch in catch block so handle it by internal.
