安装Oracle Apex 19.1后，它给出了错误PLS-00306：调用'AJAX'时参数的数量或类型错误。
虽然其他请求运行良好，但ajax调用没有。
示例：导出交互式报告时，在操作菜单上我会得到：
Error Message
1 error has occurred
Error: Internal Server Error
以下是请求调试信息。
500 Internal Server Error

现在，使用直接tomcat“localhost：8080 / ords”作为构建器，你可以使用apache来运行你的应用程序......工作正常。
取决于您升级ORDS和APEX的订单。
如果您刚刚将APEX升级到19.1，则需要运行ords java -jar ords.war验证，以便ORDS 18.4可以在APEX安装后修复它的安装。 （打破ORDS）
问候
第一个oracle apex 19.1发布有一个bug，Oracle APEX Release 19.1.0.00.15现在可以了！谢谢！
