[HPM] Error occurred while trying to proxy request

最近在用vue+express+mongodb搭建項(xiàng)目，服務(wù)器這邊是搭好了，但在前端請(qǐng)求的時(shí)候報(bào)服務(wù)器端錯(cuò)誤504
我直接訪問(wèn)127.0.0.1：3000都能獲取數(shù)據(jù)；

服務(wù)器報(bào)錯(cuò)：[HPM] Error occurred while trying to proxy request /goods from 127.0.0.1:8080 to http://127.0.0.1:3000/goods
這是index.js代理配置：

proxyTable: {
      '/goods': {
        target:'http://127.0.0.1:3000/goods',
        changeOrigin:true,
        pathRewrite:{
          '^goods':''
        }
      }
    }

這是前端請(qǐng)求：

http:function () {
      this.$axios.get('/goods').then((req,res)=>{
        let data = res.data;
        if(data.status === "0"){
          this.usurInfo = data.result;
        }else {
          this.usurInfo = [];
        }
      })
    }
