从Loriot向Google应用程序脚本错误发布状态代码为302的消息

Question

我正在尝试建立一个LoRa通信网络。

我有一个网关模块RHF0M301-915，带有覆盆子pi 3 B的PRI 2桥RHF4T002（作为Lora网关）；带有GPS的seeeduino板，RHF76-052AM。

两者都在Loriot服务器中注册。

我设法通过ABP方法将GPS数据从seeeduino板发送到Loriot服务器的仪表板。我想将数据输出到我的android移动应用程序，以向用户显示地图上的最终节点在哪里。

我选择使用HTTP Push（Loriot服务器提供的输出选项之一）。

我关注了这些guidelines。

我能够将GPS数据发送到Loriot服务器，但是HTTP推送无法将数据推送到按照指南创建的google工作表中。我在Loriot服务器的日志中收到以下错误消息：

以下代码将数据发送到了Google表格：

}

这是命令seeeduino板将gps数据发送到Loriot服务器的代码。

          }
          delay(1000 * 60 * 5);
      }
    }
    
}

我该如何处理状态代码302，我知道这与将我以前使用的目标URL重定向到某个临时URL有关。但是我不知道如何处理。
