如何解决无法将实体添加到开箱即用的jhipster项目中
我用react建立了一个jhipster网站。到目前为止，除了我在JHipster Studio中创建了一个实体并通过jhipster import-jdl {pathToDownloaded.jh}安装了一个实体外，没有任何改变。一切都安装没有错误。我没有更改控制器或其他任何东西的自动生成的代码。这是从JHiptser Studio下载的.jh文件的内容
entity MyFile {
identifier Long unique
title String required
url String
path String required
mimeType String required
fileSize Long
source String
file Blob required
}
我执行了迁移cassandra的命令，并运行构建和启动服务器。页面加载完毕，我可以使用管理员凭据登录。但是，当我导航到实体列表，创建一个新实体，填写必填字段并点击保存时，出现500错误。
我在chrome中使用了控制台，并看到以下错误。
当我单击顶部错误上的链接时，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 required to access this resource","path" : "/api/my-files","message" : "error.http.401"
}
但是此错误没有意义，我已经使用默认的管理员凭据登录。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调用。我使用管理员登录名获取令牌，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错误到未定义列名错误的不同错误的种类，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
