【报Bug】builder x 升级3.4.15后APP真机调试出现白屏问题

示例代码：

import service from 'axios';
import qs from 'qs';

import axiosAdapterUniapp from 'axios-adapter-uniapp'

const str = ""

//==================H5===============begin
/ #ifdef H5 /
str = ""
service.defaults.baseURL = "/api";
/ #endif /
//==================H5===============end

//==================MP-WEIXIN===============begin
/ #ifdef MP-WEIXIN/

str = "https://**"
service.defaults.baseURL = "";

/ #endif /
//==================MP-WEIXIN===============end

//==================APP===============begin
/ #ifdef APP-PLUS /
service.defaults.baseURL = "";
// 正式环境

str = "https://www.****server/"
// 测试环境
// const str = "http://localhost:6999/mserver/"

service.defaults.adapter = function (config) {
return new Promise((resolve, reject) => {
console.log(config)
var settle = require('axios/lib/core/settle');
var buildURL = require('axios/lib/helpers/buildURL');
uni.request({
method: config.method.toUpperCase(),
url: buildURL(config.url, config.params, config.paramsSerializer),
header: config.headers,
data: config.data,
dataType: config.dataType,
responseType: config.responseType,
sslVerify: config.sslVerify,
complete:function complete(response){
response = {
data: response.data,
status: response.statusCode,
errMsg: response.errMsg,
header: response.header,
config: config
};

        settle(resolve, reject, response);    
        }    
    })    
})    

}
/ #endif /
//==================APP===============end

// request拦截器,在请求之前做一些处理
service.interceptors.request.use(
(config) => {
config.headers["X-Requested-With"] = "XMLHttpRequest";
config.headers["Content-Type"] = "application/json; charset=UTF-8";

    if (!config.data) return config;  

    if (config.data.isUpload) config.headers["Content-Type"] = "multipart/form-data";  

    return config;  
},  
(error) => {  
    console.log(error);  
    return Promise.reject(error);  
}  

);

//配置成功后的拦截器
service.interceptors.response.use(
(response) => {

    const data = response.data;  

    if (Object.prototype.hasOwnProperty.call(data, "code")) {  
        //     程序异常 = -2,  
        // 未授权 = -1,  
        // 失败 = 0,  
        // 成功 = 1,  

        if (data.code === -1) {  
            //接口授权码无效  
            tools.message(data.message + ",请重新登录授权!", "警告");  
            // return router.push("/login");  
        }  
        if (data.code === -2) {  
            //服务端异常  
            console.log("错误",data.message)  
        }  
        if (data.code === 0) {  
            //失败  
            console.log("警告",data.message)  
        }  
    }  

    return response;  
},  
(error) => {  
    if (error.response) {  

        if (error.response.status === 401) {  
            console.log("未授权!", "错误")  

            // router.replace("/login");  
            // window.location.reload();  
        }  
    }  

    if (error.message === 'Network Error') {  
        console.log("网络连接错误!", "错误")  
        // tools.message('网络连接错误!', "错误");  
        // router.replace("/login");  
    }  

    console.log(error);  

    return Promise.reject(error.response.data);  

}  

);

export default {
/**

• @param {Object} url
• @param {Object} params params: {selectDate: selectDate,flightId: flightId},

• @param {Object} data {}
  */
  get(url, params, data) {
  return new Promise((resolve, reject) => {
  service({
  method: "get",
  url: str+url,
  params: params,
  data: data
  // data:this.qs.stringify({ //这里是发送给后台的数据
  // userId:this.userId,
  // token:this.token,
  // })
  }).then((response) => { //这里使用了ES6的语法
  console.log("request======:",
  response) //请求成功返回的数据
  resolve(response);

      }).catch((error) => {  
          reject(error)  
          // console.log("error",error) //请求失败返回的数据  
      })  
  });  

  }

}

操作步骤：

引入 import service from 'axios' 就报错

预期结果：

正常使用 import service from 'axios';

实际结果：

reportJSException >>>> exception function:createInstanceContext, exception:white screen cause create instanceContext failed,check js stack ->Uncaught SyntaxError: Unexpected token ','
