【问题描述】：
我正在与一个团队一起开展一个 uni 项目。当我在前端工作时，团队的一部分人与后端的数据库建立了连接。但是当我尝试使用来自我们的 api 的获取请求时，我的玻璃鱼日志中出现错误。我有时会在运行时遇到不同的错误。 我们正在使用持久性构建一个 Web 应用程序。 当我在浏览器中使用正确的 url 时，它会给我这些错误：
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
和：
javax.persistence.PersistenceException: [PersistenceUnit: VodafoneZiggoDB] Unable to build Hibernate SessionFactory
奇怪的是我的队友没有这个问题。我们有相同的 IDEA 和 mysql 工作台版本。我们确实有不同的 mysql 服务器版本。当我在 macOS 上工作时，他们没有。
我尝试将 javassist.jar 添加到 pom 中，并进行清理和安装，但这没有用。 我试过重新安装 IntelliJ 但没有运气。 我尝试在 pom.xml 中使用不同的 mysql 连接器版本。 我尝试在 stackoverflow 上找到解决方案，但没有成功。

当我在 mysql 连接器版本之间切换时，我也会收到 Driver#Connect 错误。
预期的结果是在浏览器和玻璃鱼日志中都没有出现这些错误。并且实际上在后端和 mysql 工作台之间建立了连接。
