I am trying to create wso2 human task where the approval has to be given by multiple owners in some sequence. I am calling human task from Asynchronous BPEL process. I am able to upload the Process and task packages successfully. But when I try to create the process instance, i am getting below error in the logs:

Code snippet for setting the workflow in Task is given below.
`<htd:peopleAssignments> <htd:potentialOwners> <htd:sequence type="all"> <htd:from logicalPeopleGroup="shippingLine"> <htd:argument name="role"> shippingLineRole </htd:argument> </htd:from> <htd:from logicalPeopleGroup="cho"> <htd:argument name="role"> choRole </htd:argument> </htd:from> </htd:sequence> </htd:potentialOwners>
`
Any idea what is going wrong here. As the task creation is working fine when workflow has single owner.
