@tlikarish Service account creation was not a problem, account permission was missing to corresponding project trigger task. It worked.
Let me summaries what is current feature and what can be enhanced related to trigger task.
1- End client who is using trigger task, can’t use bearer token due to security gap and that’s why we moved to basic authentication.
a- Some client they are calling trigger task using some program, they can use trigger task url, user id and password to connect snaplogic and good to go.
b- Some other client they are calling directly url from their website and they don’t have mechanism for authentication. It seems like we don’t have work around for this. Still I am checking what can be done over here.
2- As part of bulk submit, trigger task is not queuing the request in case previous request is running, in order to avoid this issues, workaround is disable the trigger option. But challenges here is all request running concurrently and threaddump got increased and it is depend on system(snaplex) configuration. I don’t think we have any other option for us now, in case we have other choice, we will verify.
