Promote Planning Units using Groovy

Summary: We're trying to manage approvals using Groovy but we're not able to fetch and apply actions like Promote, originate etc. using Groovy. We've followed all the steps mentioned in the Doc : Get Planning Unit Promotional Path (oracle.com).

The issue is that we're not getting the list of planning units assigned to the user and code runs successfully and we're getting response 200 & 201 but not the planning units. Manually we are able to fetch and apply all actions but not through the groovy.
