Identity Attribute Transform Errors

Hi @ethompson ,
The issue is with old value calculation. You are setting empty incase oldValue is not available & then you are splitting it which is causing error. Set the old to a default value & try. Below is working for me.

"old": {
    "attributes": {
        "input": {
            "attributes": {
                "values": [
                    "$oldValue",
                    "NA"
                ],
                "ignoreErrors": "true"
            },
            "type": "firstValid"
        },
        "delimiter": " ",
        "index": 0.0
    },
    "type": "split"
},
