Hey @Cteq3132 thanks for opening an issue, looks like Dio did not catch the error. I think we can fix this with an Interceptor

 InterceptorsWrapper(
        onError: (error, handler) {
          // Do stuff here
          handler.reject(error); // Added this line to let error propagate outside the interceptor
        },
      ),
