I'm trying to create new Job on Deploys -> Jobs in KIE Workbench. I already have a few DEPLOY jobs which were automatically created when I called "/deployments/{deploymentId}/deploy" REST API method. New job should also deploy the same unit but should be executed at the certain date. I set date, owner, DeploymentUnit, JobType, businessKey and other parameters for the new job and it's executed at the certain time, but the following error happens:

java.lang.ClassCastException: java.lang.String cannot be cast to org.jbpm.kie.services.impl.KModuleDeploymentUnit

  at org.jbpm.executor.impl.AvailableJobsExecutor.executeJob(AvailableJobsExecutor.java:153)

When DEPLOY job is automatically created, CommandContext object is serialized to RequestData field of RequestInfo. When job is executed, RequestData is deserialized to CommandContext which contains the map of parameter name -> object pairs. If job is created manually, RequestData is deserialized to CommandContext which contains the map of parameter name -> string pairs. So, there are strings where objects are expected. Therefore ClassCastException happens.

Is there any way to manually create  DEPLOY job?

Are there other ways to start unit deployment or activate process definition by date?

My goal is to schedule automatic business process version update, so that my application, connected to Workbench via remote runtime engine, uses updated process when it's time.
