I've been testing an inbound upload processor and I want to avoid overwriting manually entered information. Specifically lifecycle fields. My problem is that... it keeps replacing the value

Any help would be helpful, I think the problem is the validation before writing, I have not found another method to verify if there is information in the record before writing

{
	"processors":  
		{
			"processorType": "inboundFactSheet",
			"processorName": "load capability",
			"processorDescription": "just a POC to load capability",
			"type": "BusinessCapability",
			"filter": {
				"exactType": "BusinessCapability"
			},
			"identifier": {
				"external": {
					"id": {
						"expr": "${data.externalId}"
					},
					"type": {
						"expr": "externalId"
					}
				}
			},
			"run": 0,
			"updates":  
             {
					"key": {
						"expr": "lifecycle.active"
					},
					"values":  
						{
							"expr": "${lx.factsheet.lifecycle.active == null ?  data.active : lx.factsheet.lifecycle.active }"
						}
					],
					"optional": true
				}
            ]

}

this is the payload i’m using:

{
    "connectorType": "integracion OSB - Inbound",
    "connectorId": "inbound_osb",
    "connectorVersion": "0.0.1",
    "lxVersion": "1.0.0",
    "processingDirection": "inbound",
    "processingMode": "partial",
    "description": "Integración entre Capacidades y workspaces",
    "content": t
        {
            "type": "BusinessCapability",
            "id": "33a6e4d1-65e9-4c55-bd95-d41572388ec8",
            "data": {
                "name": "Enterprise Architecture",
                "externalId": "ENARCH",
                "active": "2021-01-01"
          }
    ]

}
