недопустимый символ 'R' ищет начало значения

Question

Я пытаюсь попасть по URL-адресу

http://localhost:33250/api/v1/edit-order-request/?order_id=1231

, появляется эта ошибка:

invalid character 'R' looking for beginning of value

Что я делаю не так?

Изменить: http_client . go

func (c *HTTPClient) Call(url string, body interface{}, h http.Header, hc string, method string) (*response.BaseResponse, error) {
    outputChannel := make(chan *response.BaseResponse, 1)
    util.FilterHeaders(&h)
    errChannel := hystrix.Go(hc, func() error {
        var res *http.Response
        var err error
        switch method {

        case util.Post:
            rbyte, _ := json.Marshal(body)
            rreader := bytes.NewReader(rbyte)
            res, err = c.httpClient.Post(url, rreader, h)
        case util.Put:
            rbyte, _ := json.Marshal(body)
            rreader := bytes.NewReader(rbyte)
            res, err = c.httpClient.Put(url, rreader, h)
        case util.Patch:
            rbyte, _ := json.Marshal(body)
            rreader := bytes.NewReader(rbyte)
            res, err = c.httpClient.Patch(url, rreader, h)
        case util.Get:
            res, err = c.httpClient.Get(url, h)
            log.Info().Msgf("res %v",res)
        }
        if err != nil {
            log.Error().Err(err).Msgf(method+" api failed: %s", body)
            return err
        }
        defer res.Body.Close()
        var baseResponse response.BaseResponse
        d := json.NewDecoder(res.Body)
        d.UseNumber()
        err = d.Decode(&baseResponse)
        if err != nil {
            log.Error().Err(err).Msgf("Failed to decode the response for url %s", url)
            return err
        }
        baseResponse.HTTPStatusCode = res.StatusCode

        outputChannel <- &baseResponse
        return nil
    }, func(err error) error {
        return err
    })
    select {
    case res := <-outputChannel:
        log.Info().Msgf(method+" response for URL %s, BODY %s , HEADER %s, RESPONSE %s", url, util.ToJSON(body), util.ToJSON(h), util.ToJSON(res))
        return res, nil
    case err := <-errChannel:
        log.Info().Msgf("Error received on error channel for URL %s", url)
        return nil, err
    }
}

Заглушка:

var EditServiceGetConversationIdOmtTaskIdNonEmptyStub = &wiremock.Stub{
    Request: wiremock.Request{
        Method:     "GET",
        UrlPattern: "/api/v1/edit-order-request/"+"?order_id=1231",
    },
    Response: wiremock.Response{
        Status: 200,
        Body:   EditServiceGetConversationIdOmtTaskIdNonEmptyResponse,
    },
}

var EditServiceGetConversationIdOmtTaskIdNonEmptyResponse = "{\"statusCode\":0,\"statusMessage\":\"success\",\"data\":{\"order_id\":1231,\"edit_reason\":\"EDIT\",\"crm_conversation_id\":\"p-qwr-1234\",\"omt_task_id\":\"1231\"}}"

Когда в заглушке я использую параметр Url, эта ошибка исчезает. Может ли кто-нибудь объяснить мне причину этого?
