我有一个GCP BigQuery示例设置，我想设置我的网页写入数据到一个特定的数据/集合。我已经成功地建立了wix.com托管网站和GCP之间的连接。我已经证明了在wix.com GUI中手动编辑记录。现在我想通过代码来完成这一点。下面的代码旨在做到这一点。代码执行w/out错误，但是数据实际上并没有被写入GCP BigQuery表。我假设我错过了提交记录更改的最后一步，但我只是不确定那是什么。任何帮助都非常感谢，我意识到我是JS新手，所以请耐心一点：-）。
itemID是调用函数时传递的项ID。

let item = $w('#dataGCPOperational').getCurrentItem();
saveData(item._id);

export function saveData(itemID){
  let userEmail = currentMember.getMember().then((member) => {
          return member.loginEmail;
          
      })
  let instagramHandle = $w('#inputInstagram').value
  console.log("instagramHandle " + instagramHandle)
  let market = $w('#dropdownMarket').value
  console.log("market " + market)
  //let optIn2023 = $w('#checkbox2023OptIn').value
  let howManyYrs = $w('#inputYearsParticipated').value
  console.log("howManyYrs " + howManyYrs)
  let howManySixteen = $w('#inputYearsCompleted16').value
  console.log("howManySixteen " + howManySixteen)
  let participatedBefore = $w('#checkboxParticipatedBefore').value
  console.log("participatedBefore " + participatedBefore)
  let sixteenBefore = $w('#checkboxCompleted16Before').value
  console.log("sixteenBefore " + sixteenBefore)
  let exclProgressBoard = $w('#checkboxExcludeFromLeaderboard').value
  console.log("exclProgressBoard " + exclProgressBoard)

  wixData.get("gcpOperationalDB/tblSTMParticipantData", itemID)
  .then(item => {
      item.email = userEmail
      item.instagram = instagramHandle;
      item.market = market
      item.numYearsParticipated = howManyYrs
      item.numYearsSixteen = howManySixteen
      item.participatedBefore = participatedBefore
      item.recordedSixteen = sixteenBefore
      item.excludeFromLeaderboard = exclProgressBoard
    })
    return $w('#dataGCPOperational').save()
    .then(() => {
        console.log("Item updated successfully");
    })
    .catch((err) => {
        console.log("Failed to update item: " + err);
    });

}

我希望将这些变量的值写入到使用$w('#dataGCPOperational')引用的GCP表中的相应字段中。

let instagramHandle = $w('#inputInstagram').value
  let market = $w('#dropdownMarket').value
  let howManyYrs = $w('#inputYearsParticipated').value
  let howManySixteen = $w('#inputYearsCompleted16').value
  let participatedBefore = $w('#checkboxParticipatedBefore').value
  let sixteenBefore = $w('#checkboxCompleted16Before').value
  let exclProgressBoard = $w('#checkboxExcludeFromLeaderboard').value
