Steps/Sample code to reproduce the issue

Create an adrule :

hash={
      "name": "unpause_rule",
      "status": "DISABLED",
      "evaluation_spec": {
        "evaluation_type": "SCHEDULE",
        "filters": [
          {
            "field": "impressions",
            "operator": "LESS_THAN",
            "value": 1
          },
          {
            "field": "entity_type",
            "value": "ADSET",
            "operator": "EQUAL"
          },
          {
            "field": "time_preset",
            "value": "THIS_MONTH",
            "operator": "EQUAL"
          }
        ]
      },
      "execution_spec": {
        "execution_type": "UNPAUSE"
      },
      "schedule_spec": {
        "schedule_type": "SEMI_HOURLY"
      }
    }
ad_account.adrules_library.create(hash)

And then get its evaluation_spec ad_account.adrules_library.first.evaluation_spec
