[英]"Object reference not set to an instance of an object" error when trying to update a Product with ShipStation's API
I'm having trouble updating a product in Shipstation.我在 Shipstation 中更新产品时遇到问题。
I'm been using these 2 links to see how I should format the response:我一直在使用这两个链接来查看我应该如何格式化响应:
https://www.shipstation.com/docs/api/products/update/ https://www.any-api.com/shipstation_com/shipstation_com/docs/Products/_products_productId_/PUT https://www.shipstation.com/docs/api/products/update/ https://www.any-api.com/shipstation_com/shipstation_com/docs/Products/_products_productId_/PUT
I believe I'm following it correctly, but I always get a 500 error message saying "Object reference not set to an instance of an object".我相信我正确地遵循它,但我总是收到一条 500 错误消息,说“对象引用未设置为对象的实例”。
I've been using the GET request to get the product's attributes.我一直在使用 GET 请求来获取产品的属性。 Then I update the attributes that need to be changed, and store it in
data
(which is an array of objects).然后我更新需要更改的属性,并将其存储在
data
中(这是一个对象数组)。 Then I use the PUT request to send the data.然后我使用 PUT 请求发送数据。
This is the relevant code:这是相关代码:
function updateProducts(authString, data) {
var baseProductUrl = `https://ssapi.shipstation.com/products/`;
for(var d = 0; d < data.products.length; d++) { //for each product I'd like to update...
var raw = data.products[d];
raw = JSON.stringify(raw);
var requestOptions = {
method: 'PUT',
headers: {
"Authorization": `Basic ${authString}`,
"Content-Type": `application/json`,
},
body: raw,
redirect: 'follow'
};
var productUrl = `${baseProductUrl}${data.products[d].productId}`;
UrlFetchApp.fetch(productUrl, requestOptions);
}
}
This is what raw
(the data I'm sending to ShipStation) looks like: The null values are simply what I receive from the GET request.这就是
raw
(我发送到 ShipStation 的数据)的样子: null 值就是我从 GET 请求中收到的值。 I'd prefer those attributes stay empty.我希望这些属性保持空白。
{"aliases":null,

"customsValue":9.99, //attribute I'd like to update
"customsTariffNo":null,
"customsCountryCode":"US",
"noCustoms":null,
"tags":null}
So does anyone have any hints, or has anyone used ShipStation's API before and done a PUT request?那么有没有人有任何提示,或者有没有人使用过 ShipStation 的 API 并完成了 PUT 请求? What am I missing?
我错过了什么?
In your script, how about the following modification?在您的脚本中,如何进行以下修改?
var requestOptions = {
method: 'PUT',
headers: {
"Authorization": `Basic ${authString}`,
"Content-Type": `application/json`,
},
body: raw,
redirect: 'follow'
};
var requestOptions = {
method: 'PUT',
headers: {
"Authorization": `Basic ${authString}`,
},
pyaload: raw,
contentType: "application/json",
};
