Hi guys,

Does anyone know if there is a way to copy the @timestamp value from winlogbeat json to a separate field (for troubleshooting purposes) using winlogbeat.yml file?

I'm trying to use the copy fields processor:

```
  - copy_fields:
      fields:
        - from: @timestamp
          to: original_event_timestamp

```

But I just get: Failed to copy fields in copy\_fields processor: could not fetch value for key: @timestamp, Error: key not found
