在API测试中发送发布请求时出现错误422

Question

对于一个Web应用程序，我试图通过使用Java中的RestAssured框架编写api测试，并且该场景有2个步骤，如下所述；

1. 通过键入客户信息来注册客户。
2. 按下注册按钮后，应在下一页输入手机号码和otp密码。另外，所关注的密码等于客户手机号码的后四位。

我的第一个帖子请求在第一步中运行良好，但第二步却遇到422错误，正文响应给出了以下错误；

“错误”：[{“代码”：{“名称”：“ MemberNotFoundException”，“值”：“ MembershipService_M0002”}，“消息”：“成员不存在。”}]}

可能是什么原因？
