Empty Variables in Veloctiy

[colin_mckibben]

firstValid is the best solution for correcting null values. Here is a simple example that will look for a mail attribute from AD, and if it is not available it will use the static string value none.

{
  "id": "Determine Email",
  "type": "lower",
  "attributes": {
    "input": {
      "type": "firstValid",
      "attributes": {
        "values": [
          {
            "attributes": {
              "attributeName": "mail",
              "sourceName": "Active Directory"
            },
            "type": "accountAttribute"
          },
          {
            "attributes": {
              "value": "none"
            },
            "type": "static"
          }
        ]
      }
    }
  }
}
