element-ui 自定义表单验证 请求后端接口报错 callback is not a function?

在浏览器中打断点发现会执行两次这个函数,第一次验证的时候没有任何问题,正常请求接口,但是不知道为什么会执行第二次。

import { checkCode } from "@/api/sales/globalWares";

var checkCode = (rule, value, callback) => {
      if (!value) {
        callback(new Error('请输入编码'));
      } else {
        checkCode({ waresCode: value }).then(res => {
          if (res.data > 0) {
            callback(new Error('编码重复'));
          } else {
            callback();
          }
        });
      }
    }
rules: {
        waresCode: [
          { required: true, validator: checkCode, trigger: 'blur' }
        ],
        shortName: [
          { required: true, message: "商品简称不能为空", trigger: "blur" }
        ]
      },

验证部分代码就是这样的,不知道有没有哪位大佬能帮忙解答一下。。。

导入的函数checkCode和验证用的函数重名,导致他调用到自己,循环调用
