Query DeploymentEntity throw NullPointerException

Flowable Engine
1

hi:
When my code runs to ：

 ProcessDefinition pde = org.flowable.engine.impl.util.ProcessDefinitionUtil.getProcessDefinition(task.getProcessDefinitionId());

 or

 DeploymentEntity deploymentEntity = org.flowable.engine.impl.util.CommandContextUtil.getProcessEngineConfiguration()
            .getDeploymentEntityManager().findById(processDefinitionEntity.getDeploymentId());

Always throw NullPointerException exceptions ，why？ These Util tool classes is not supported like that？

then i Modify code like this：

DeploymentEntityManager dem = processEngineConfiguration.getDeploymentEntityManager();
DeploymentEntity deployment = dem.findById(pde.getDeploymentId());

Still throw an exception，in debug mode ，i find in class Context.class method getCommandContext() is null！
please How do I operate it?

Best regards

Hi Zhiyin,

manager’s findById can be used only in the command context (see usages).
Use repository service to query for deployments by id.
