System.ListException: Duplicate id in list: with Database.upsert (list,externalid,false)

Hi Devs,

I am receiving "Duplicate id in list" error in the below line and I know "requests" has duplicate ids, isn't it supposed to store success or error in "upserRslt"?

Database.UpsertResult [] upserRslt = Database.upsert(requests, externalIdField, false);

Partial success is not working even with Database.upsert(false) parameter, I am using the above code in the Queueable class, has anyone faced this issue?

Thanks!

@Abhinav thanks for your response, my query was not to fix duplicate id. My concern was, it should not throw exception when I am using Database.upsert with false parameter.
