this.commandExecutor is null when calling process instance api

vikash_patel — Fri, 30 Aug 2024 10:20:46 GMT

We are using APS 24.2.
We have upgraded the APS 1.11 to 24.2.
3 spring projects are there app-main and app-ext and app-assembly,we have also upgraded it with compatible latest version of APS 24.2
APS is successfully upgraded to 24.2.
app-main and app-ext are the spring project which have the extended code of APS classes.
It has overridden some default classes.

public class CustomAlfrescoProcessInstanceService extends AlfrescoProcessInstanceService

We are calling below api to start process

URL:
http://hostort/activiti-app/api/enterprise/process-instances

Request data:
{"name":"Ticket Initiation - 08/28/24 2:46:10PM","processDefinitionId":"DEMOTicketInitiationNew:1:112556","values":{"supporting_document":null,"parent_ticket_id":null}}

Issue is : When we are trying to start the process it gives below errors.
