AFNetworking 3.0 Data cannot be read because it is not in the correct format

Question

There are other questions with similar names, but none of them helped me. I have to send a request PUTto the server to change the destination status, so I made this method -(void)appointmentStatusChangedTo:(NSString *)statusID atAppointmentID:(NSString *)appointmentIDin which I set the URL and parameters as

NSString *string = [NSString stringWithFormat:@"%@/API/Appointments/3",BaseURLString];
    NSDictionary *para = @{
                           @"AppointmentStatusId":statusID,
                           @"ID":appointmentID
                           };

Then I made a url request like

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

    NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"PUT" URLString:string parameters:para error:nil];

After that, I set the header for the authorization token as

 NSString *token = [NSString stringWithFormat:@"Bearer %@",[[NSUserDefaults standardUserDefaults] objectForKey:@"userToken"]];

    [req setValue:token forHTTPHeaderField:@"Authorization"];

So I call it

[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error){
        if (!error) {
            if (response) {
                NSLog(@"Respose Object: %@",responseObject);
                [self.patientsAppointmentsTableView reloadData];
            }
        }
        else {
    // NSLog(@"Error: %@, %@, %@", error, response, responseObject);
    NSLog(@"Error: %@", error.localizedDescription);
}
        }] resume];

Now it successfully sends data to the server, but as an answer I get

Error: The data cannot be read because it is incorrect format.

Answer 1

:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
[serializer setStringEncoding:NSUTF8StringEncoding];

manager.requestSerializer=serializer;
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager GET:url parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
        NSLog(@"%@",responseObject);
        self.responseHandlers(YES,responseObject);
    } failure:^(NSURLSessionTask *operation, NSError *error) {
        self.responseHandlers(NO,nil);
    }];
