TypeError：無法讀取 null NodeJs 請求模塊的屬性“名稱”

Question

我想用請求模塊發送一個發布請求。 我的代碼是這樣剪斷的：

 let formData = new FormData();

   myArray.map((param, index) => {
      formData.append(param.name, param.value)
    })

    formData.append('file', fs.createReadStream(file.location), { filename: file.name });

    var options = {
      'method': 'POST',
      'url': 'https://shopify-video-production-core-originals.s3.amazonaws.com/',
      'headers': {
      },
      formData: formData,
    };

    let requestProm = async () => {
      return new Promise(resolve => {
        request(options, function (error, response) {
          if (error) {
            logger.error("Video Upload Failed")
            console.log(error)
          } else {
            logger.info("Video Upload Successfull");
            resolve(response);
          }
        })
      })

    }

    await requestProm()

但我收到一個錯誤：

類型錯誤：無法讀取 null 的屬性“名稱”

為什么我收到此錯誤？ 請幫忙！

編輯：我控制了我的 formData。 沒有 null 名稱值。 我在互聯網上搜索，但找不到任何解決方案。 所以，我的 formData 是這樣的：

Answer 1

顯然，表單數據已經由請求承諾處理。 您可以將表單數據作為 object 傳遞。 檢查這個

Answer 2

檢查 myArray 元素的類型

Answer 3

Cannot read property '' of null的屬性不存在。 您可以做的是記錄文件，然后檢查屬性“名稱”是否存在。 請記住：console.log() 是你在 nodejs 中最好的朋友（以及一般的編程）
