如何解决无法将实体添加到开箱即用的jhipster项目中？我用react建立了jhipster网站。到目前为止，除了我在JHipster Stu中创建了实体并通过jhipster import-jdl {pathTwnloaded.jh}安装了实体外，没有任何改变。一切都安装没有。我没有更改控制器或其他任何东西的的。这是从JHiptser Stu下载的.jh的
entity MyFile { identifier Long unique title String url String path String mimeType String fileSize Long source String file Blob
}
我执行了迁移cassandra的命令，并运行构建和启动服务器。加载完毕，我可以使用凭据。但是，当我导航到实体列表，创建新实体，填写必填字段并点击保存时，出现500。
我在chrome中使用了控制台，并看到以下。
当我单击顶部上的时，将带我到以下消息
{ "type" : "https://www.jhipster.tech/problem/problem-with-message","title" : "Unauthorized","status" : 401,"detail" : "Full authentication is to access this resource","path" : "/api/my-files","message" : "error.http.401"
}
但是此没有意义，我已经使用认的凭据。我缺少一些允许实体创建的设置吗？
我已采取的其他调试步骤是尝试使用Postman进行API。我使用名令牌，并将其分配为进行呼叫的载体凭证，这似乎摆脱了401。它确实成功返回了GET上的空列表，但POST无法正常工作，我得到了很多从无效类型到未定义列名的不同的种类，这取决于我要发送的json数据。
编辑：运行gradlew的本地控制台中的stacktrace
