Hi All! Documentation shows

hour

as an option for

detection_period

on

elementary.volume_anomalies

test. However, when I set

detection_period

to

hour

as below

detection_period:
   period: hour
   count: 1

I'm getting a Compilation Error

Missing mandatory configuration: ['backfill_days']

How do I correctly specify an hourly

detection_period

? Please help. Below is my complete test setup:

- elementary.volume_anomalies:
    where_expression: "<expr>"
    anomaly_direction: drop
    anomaly_sensitivity: 1
    timestamp_column: "raw_sent_at"
    time_bucket:
      period: hour
      count: 1
    detection_period:
      period: hour
      count: 1
    training_period:
      period: day
      count: 21
    seasonality: hour_of_day
    config:
      severity: error
