Starting job via Orchestrator API - stuck in PENDING state


#1

I’m able to create job using StartJob API ( https://platform.uipath.com/odata/Jobs/UiPath.Server.Configuration.OData.StartJobs) however it does not execute at all and stuck in Pending state.
Also, when I try to initiate another one it does not create another entry on the job list.
I’m using Postman by the way just for testing.

Below are the parameters I’ve supplied, is there anything I’m missing?

UPDATE:
My mistake. I specified the wrong robot ID.
On the job capacity though, per testing, I can only queue up at most 2 jobs when continuously initiating job thru API. Starting at the third one it won’t create new entry on the job list.
