ProcessEngineException: Process engine persistence exception

Camunda 7 Topics

Hello, When I installed Camunda using Docker and modeled and deployed a workflow that contains a service task, and I executed http://localhost:8080/engine-rest/external-task/fetchAndLock, an error is displayed to me:
Caused by: org.apache.ibatis.ognl.OgnlException: size [java.lang.reflect.InaccessibleObjectException: Unable to make public final int java.util.HashMap$Values.size() accessible: module java.base does not “opens java.util” to unnamed module @44e81672]

{
    "type": "ProcessEngineException",
    "message": "Process engine persistence exception"
}

Hello my friend!

I’m not sure, but this could certainly be related to the version of your dependencies and their compatibility with your version of Java or Camunda.

One suggestion would be to take a look at your dependencies and check their compatibility between their versions.
