Hi! I tried with similar config like below and also didn't see the custom field `log_type`.

```auto
- module: iis
  # Access logs
  access:
    enabled: true
    var.paths: ["D:/Logs/W3SVC1/*.log"]
    exclude_line: ['^.*ELB-HealthChecker.*$']
    fields:
      log_type: iisnonpro

  # Error logs
  error:
    enabled: false

```

I also gave [Custom Fields with Module Config](https://discuss.elastic.co/t/custom-fields-with-module-config/174601/2) a try, no luck. I will look into this a bit more and get back to you. Thank you for posting here!
