403调用Autodesk Forge的DerivativeApi时出错

Autodesk Forge 的 导数API 无法使用我的客户端id和机密。API返回未经授权的错误, {状态代码:403,状态消息:'未授权} .

但它们使用示例的客户id/机密(来自 https://github.com/Autodesk-Forge/forge-api-nodejs-client/blob/master/samples/dmSample.js ).

使用免费帐户调用派生EAPI(用于翻译)是否有任何限制?还是我该做点什么?

下面是示例代码。。。

var ForgeSDK = require('forge-apis');

// TODO - insert your CLIENT_ID and CLIENT_SECRET
// Below id/secret from the sample are working, but mine is not.
 var CLIENT_ID = 'wmizntnpzCJxPGF9lxsIiTZGbGO2cJqw',
   CLIENT_SECRET = 'g5IPJwvhOHcrdbFy';

var derivativesApi = new ForgeSDK.DerivativesApi();

// Initialize the 2-legged oauth2 client
var oAuth2TwoLegged = new ForgeSDK.AuthClientTwoLegged(CLIENT_ID, CLIENT_SECRET,
  ['data:write', 'data:read', 'bucket:read', 'bucket:update', 'bucket:create'], true);

function defaultHandleError(err) {
  console.error('\x1b[31m Error:', err, '\x1b[0m');
}

oAuth2TwoLegged.authenticate().then(function (credentials) {
  console.log("**** Got Credentials", credentials);
  derivativesApi.getFormats({}, oAuth2TwoLegged, oAuth2TwoLegged.getCredentials()).then(res => {
    console.log(res);
  }, defaultHandleError);
}, defaultHandleError);

谢谢
