Hey Jason,

When asking a question on this forum, please format any code with the `</>` button, as explained [here](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It makes it much easier to read. 🙂

Your script has several issues, the most important of which is that you're using the `doc['field']` notation to access field values. That notation only works at query and aggregation time. At index time, you need to access fields with the `ctx.field` notation.

The following pipeline should work:

```auto
PUT _ingest/pipeline/addWeek
{
  "description": "check weekend by using alrm_occr_ddt.date.dayOfWeek",
  "version": 1,
  "processors": [
    {
      "pipeline": {
        "if": "def dayOfWeek = OffsetDateTime.parse(ctx.alrm_occr_ddt).getDayOfWeek(); return (dayOfWeek == DayOfWeek.SATURDAY || dayOfWeek == DayOfWeek.SUNDAY)",
        "name": "weekend_true"
      }
    }
  ]
}

```
