我正在尝试使用grails和neo4j开发一个示例应用程序。我使用的是grails 3.0.8。我已经安装了neo4j插件,并按照文档中提到的说明进行操作。我已经更新了application.yml以包含neo4j凭据。我的application.yml看起来像这样。

代码执行正常,但是当我尝试创建域的实例时,我得到这样的错误。
ERROR org.grails.web.errors.GrailsExceptionResolver - IllegalStateException occurred when processing request: [GET] /person/index

我完全根据文档完成了此配置,那么为什么我会收到此错误。是不是新版本的grails与neo4j存在兼容性问题,还是我在配置中犯了一些错误。
