这个错误信息表明在调用远程系统的`getUserListByUserIds`接口时出现了内部服务器错误（Internal Server Error）。具体的错误信息是`{"timestamp":"2023-07-24 18:50:53","status":500,"error":"Internal Server Error","path":"/user/getUserListByUserIds"}`。

这种错误通常是由于远程服务器端的代码逻辑问题或者服务器资源不足导致的。你可以检查远程系统的日志文件，查找更详细的错误信息，以便排查问题。同时，你还可以联系远程系统的开发团队，共同解决这个问题。
