用户提交注册信息后，使用 watch 方法成功监听到数据已提交。然而，当我在数据提交后立即进行查询时，却无法获取到刚刚提交的数据。

补充：如果新建数据后，刷新小程序，调用同一个查询函数，会获取到数据。

app.router("SignUp", async (ctx, next) => {
      const { nickName, documentType, nationality } = event.value;
      const collections = [
         {
            name: "Users",
            data: {
               nickName,
               nationality,
               open_id: wxContext.OPENID,
               status: status.PENDING_REDRIVE,
            },
         },
         {
            name: "CertData",
            data: {
               documentType,
            },
         },
      ];

      try {
         const result = await db.runTransaction(async (transaction) => {
            const uploadPromises = collections.map(async (collection) => {
               const params = {
                  unionid_id: wxContext.UNIONID,
                  createAt,
                  ...collection.data,
               };

               const { _id } = await transaction.collection(collection.name).add({ data: params });
               return { _id, type: collection.name };
            });

            return Promise.all(uploadPromises);
         });

         ctx.body = { data: result };
      } catch (error) {
         console.error("Transaction error: ", error);
         ctx.body = { error: error.message };
      }
   });
