我们的客户遇到嵌入式发送窗口的一些零星问题 - 偶尔它会尝试加载，但随着DocuSign徽标下方的进度条接近完成而失败。当我们从Chrome或Edge检查控制台窗口时，我们也会看到以下错误：
HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier).
(XHR)GET - https://app.docusign.com/api/accounts/XXXXXXXXXXXXXX/envelopes/XXXXXXXXXX/lock?cachebuster=0.9774476769958655

最后，在尝试调查此问题时，我在DocuSign管理界面上收到了以下500错误，遗憾的是客户服务无法提供帮助：
Error on Docusign site: 500 error. Transaction Id: T34364871276903272031
如果有人对可能发生的事情有任何见解，我真的很感激一些指导！
