接口报错 cannot read properties of undefined (reading 'then')

问题

遇到一个很奇怪的问题，接口返回值为 undefined

代码如下：

// 归档/解档
archiveAction(actionType, row) {
  const ids = row && row.id ? row.id : this.ids;
  const tip = row && row.id ? `“${row.projectName}”` : "所勾选的";
  const actionLabel = actionType === "archive" ? "归档" : "解档";
  this.$modal
    .confirm(`是否确认${actionLabel}${tip}项目？${actionLabel}后可编辑`)
    .then(() => {
      this.$modal.loading(`正在${actionLabel}，请稍后……`);
      if (actionType === "archive") {
        project.archiveProject(ids).then((res) => {
          console.log({ res });
          this.$modal.msgSuccess(`${actionLabel}成功`);
          this.getList();
        });
      } else {
        project.unArchiveProject(ids).then((res) => {
          console.log({ res });
          this.$modal.msgSuccess(`${actionLabel}成功`);
          this.getList();
        });
      }
    })
    .catch((err) => {
      console.log(err);
    })
    .finally(() => {
      this.$modal.closeLoading();
    });
},

解决

后来发现是接口文档封装有问题：

// 解档：
// 错误写法
const unArchiveProject = (ids) => {
  request.put("/project/project/reArchive?ids=" + ids);
};

// 正确写法
 const unArchiveProject = (ids) => request.put("/project/project/reArchive?ids=" + ids);
