Steps to Reproduce

I have API, and it gives me 500 errors in Postman, but when I test it in Dio, it gives me DioException [unknown]: null, Error: HttpException: Connection closed while receiving data
but other errors like 400 or 401 are ok, and i can figure out what error happened

Expected Result

response.statusCode == 500

Actual Result

DioException [unknown]: null
Error: HttpException: Connection closed while receiving data
