Hi there!
We are using Camunda 7.9 with engine-api inside the spring-boot stack.
We get a recurrent problem where some activities with delegate expression are failing with the following stack:
2021-05-07 21:51:26.431 ERROR 1 — [aTaskExecutor-2] org.camunda.bpm.engine.context : ENGINE-16006 BPMN Stack Trace:

We don’t know what we can do because when this error occurred, we can move the instance activity anymore. I can cancel and restart it, but the error remains.
