Issue Summary

Duplicate objects are created if the key and any additional attributes are marked as identifiers in the import mapping configuration, even if those match the attribute values of existing objects.

Steps to Reproduce

1. Use an object type or create one that has additional custom attributes and have an object created on it. Suppose those are the object attributes:

   Key	Name	Your attribute
   OBJ-1	Your object name	Attribute value

1. Create a csv import configuration using the following csv as example:

   Key,Name,Attr
   OBJ-1,Your object name,Attribute value
   

1. Map all those attributes on the import configuration, but mark both Key and Your attribute as identifiers.

NOTE: The same behaviour happens with External System JSON import process as well mentioned in the documentation "https://developer.atlassian.com/cloud/assets/imports-rest-api-guide/schema-and-mapping/".

Expected Results

As an object already exists matching the identifiers values, no new objects should be created and the existing object should be updated.

Actual Results

Duplicate objects are created.

Workaround

The only known workaround at the moment is leaving only the Key attribute as an identifier.
