由于没有注意查看通知消息，微信云开发资源过期了几天，后来续费成功后，发现之前能正常使用的接口一下错误，请问是什么原因？

<Error: cloud.callFunction:fail Error: errCode: -501003 exceed request limit | errMsg: Request exceeded the limit (callId: 1670289208859-0.06941961940265085) (trace: 9:13:28 start->9:13:29 system error (Error: errCode: -501003 exceed request limit | errMsg: Request exceeded the limit), abort)>

我们的接口调用代码大致如下

    wx.cloud.init()
    wx.cloud.callFunction({
      name: 'getSession',
      data: {
        groupId: groupId,
        timestamp: timeStamp,
        nonce: nonceStr
      }
    }).then(res => {
      console.log('signature', res)
      ...
      省略代码
      ...
    }).catch(e => {
      console.log(e)
    })
