In the orchestrator-backend plugin, the abort action is implemented by using the DataIndex as a gateway for aborting a workflow.

As recommended by sonataflow's maintainer, to abort a workflow, a DELETE should be send to the workflow running instance.

Therefore the implementation should be changed.
 

A sample of curl request to abort a workflow:

curl -X DELETE http://create-ocp-project-sonataflow-infra.apps.ocp414.lab.local/management/processes/create-ocp-project/instances/afd7322c-4f75-4442-b508-1b3c1c11b0dd    -H "Content-Type: application/json"
