Hello All,
We have deactivated the "Handoff to sales 7.8.0", and we have implemented our custom process for it. But the OOTB BP gets triggered from its parent BP "Lead management 7.8.0".
Approach 1:
I have overridden the process "Lead management 7.8.0" by removing the Sub-Process "Handoff to sales 7.8.0" and saving it in a newer version.
Ref Img,

Also updated the system setting value of "LeadmanagementProcess" to the newer BP name. But when we try to run the flow the BP is not triggered and there is no error in the console when tried to debug, it's getting the right process from the value from SysSetting, but for no reason, the process is not been triggered and no logs found.
Approach 2:
I have overridden the process "Handoff to sales 7.8.0", in such a way when the process gets triggered it will terminate by not performing any logic.
Ref Image,

But when we run the flow it throws the below error.

Kindly, help us in identifying best way not to trigger "Handoff to sales 7.8.0" process ?
