Pipeline trigger is always updated due to "id" field

[max-rocket-internet]

I have a pipeline with a trigger that looks like this:

  "triggers": [
    {
      "cronExpression": "0 3 14 ? * SUN *",
      "enabled": false,
      "type": "cron"
    }
  ],

But when the trigger is created it is assigned an id and looks like this in Spinnaker:

  "triggers": [
    {
      "cronExpression": "0 3 14 ? * SUN *",
      "enabled": false,
      "id": "bcd48c7f-36e4-4c4a-870d-deb95d4e963a",
      "type": "cron"
    }
  ],

Then terraform removes the id key on every apply. Is this a bug?
