DocuSign API身份验证问题

Question

我只是尝试使用Docusign API for NodeJS来为正在构建的应用程序获取文档签名集成。 我认为我已经完成了基本的身份验证握手。 我在/docusign和/docusign/auth创建了测试路由，并且可以使用以下代码获取访问令牌。

我只想从已经以临时文件上传的文档中获取电子邮件中的测试签名链接，但是createEnvelope调用最终会出现错误：

USER_AUTHENTICATION_FAILED One or both of Username and Password are invalid. Invalid access token

provide.generateAccessToken = (req, res, next) => {
apiClient.generateAccessToken(integratorKey, clientSecret, req.query.code, function (err, oAuthToken) {

    console.log(oAuthToken);
    apiClient.setBasePath(basePath);
    //IMPORTANT: In order to access the other api families, you will need to add this auth header to your apiClient.
    apiClient.addDefaultHeader('Authorization', 'Bearer ' + oAuthToken.accessToken);
    var envelopesApi = new docusign.EnvelopesApi();
    envelopesApi.apiClient.addDefaultHeader('Authorization', 'Bearer ' + oAuthToken.accessToken);
    apiClient.getUserInfo(oAuthToken.accessToken, function (err, userInfo) {
        console.log("UserInfo: " + userInfo);
        // parse first account's baseUrl
        // below code required for production, no effect in demo (same
        // domain)
        //apiClient.setBasePath(userInfo.accounts[0].baseUri + "/restapi");
       // create a new envelope object that we will manage the signature request through
        var envDef = new docusign.EnvelopeDefinition();
        envDef.emailSubject = 'Rental Application';
        envDef.templateId = '66c8c9cf-xxx-xxxx-xxxx-xxxxxxxx';

        // create a template role with a valid templateId and roleName and assign signer info
        var tRole = new docusign.TemplateRole();
        tRole.roleName = 'Applicant';
        tRole.name = 'test';
        tRole.email = 'myemailtest@gmail.com';

        // create a list of template roles and add our newly created role
        var templateRolesList = [];
        templateRolesList.push(tRole);

        // assign template role(s) to the envelope
        envDef.templateRoles = templateRolesList;

        // send the envelope by setting |status| to 'sent'. To save as a draft set to 'created'
        envDef.status = 'sent';

        // use the |accountId| we retrieved through the Login API to create the Envelope
        var accountId = userInfo.sub;

        // instantiate a new EnvelopesApi object

        // call the createEnvelope() API
        envelopesApi.createEnvelope(accountId, {'envelopeDefinition': envDef}, function (err, envelopeSummary, response) {
        if (err) {
            return next(err);
        }
        console.log('EnvelopeSummary: ' + JSON.stringify(envelopeSummary));
        return JSON.stringify(envelopeSummary);
        });
    });
});

}

任何帮助我指出正确方向的帮助将不胜感激！

谢谢！

代替

    var envelopesApi = new docusign.EnvelopesApi();

尝试

    var envelopesApi = new docusign.EnvelopesApi(apiClient);
