I am using the Python package simple_salesforce to bulk insert instances of a custom object. The custom object has Account Id as a foreign key, which I am inserting during the bulk insert.

I'm seeing an error in my bulk data load logs for Duplicate Id, which I have determined is referring to Account Id. I'm not sure why this would be flagged, since Account Id is not the primary key of the custom object. A support rep told me to look into my automation for this object, but I'm not sure where to start. What are some possible causes of this issue?
