Cannot create ticket after SOAR platform update

[edthedev]

Context

It looks like Splunk has affected something in the new platform release of SOAR (6.3.1.176) that's causing the create TDX ticket action to fail with the following error:

'create_a_ticket_in_tdx'  on asset 'tdx-soar1' completed with status: 'failed'. Action Info: Size : 1.31 KB : [{"app_name":"Team Dynamix","asset_name":"tdx-soar1","param":{ ...redacted for ticket, see chat if needed... },"status":"failed","message":"handle_action exception occurred. Error string: ''notify''"}]

We think our current playbook is only still running because it was made on the old platform version and if you were to make a new playbook that ran that action it would likely throw the same error.
