In audit trail for the events which we have created via API doesn't have username

Terraform

While creating Project via API, I am getting audit trails as

 "auth": {
                "accessor_id": "user-RDqgJtWR2NYUCxLH",
                "description": "api-org-TestQAOrganization-34AHReQmnB",
                "type": "Client",
                "impersonator_id": null,
                "organization_id": "org-4LxW3hQCLUw6mkfY",
                "organization_name": "TestQAOrganization"
            },

But while creating project via UI I am getting below response in audit trail:

"auth": {
                "accessor_id": "user-9YAht1og9nhNfE2X",
                "description": "fabric-ds-test",
                "type": "Client",
                "impersonator_id": null,
                "organization_id": "org-4LxW3hQCLUw6mkfY",
                "organization_name": "TestQAOrganization"
            },

I am using same organization token via API, still it is showing differently. But in user access we are not able to find this user as part of the organization(“api-org-TestQAOrganization-34AHReQmnB”)
