Event do not pass Schema validation

For engineers
1

I have unstructed event schema and it does not accept incoming event. Error that I get:

object instance has properties which are not allowed by the schema: ["offer","paymentMethod"]\n level: "error"\n schema: {"loadingURI":"#","pointer":""}\n instance: {"pointer":""}\n domain: "validation"\n keyword: "additionalProperties"\n unwanted: ["offer","paymentMethod"]\n"

Schema:

{
  "$schema": "http://iglucentral.com/schemas/com.snowplowanalytics.self-desc/schema/jsonschema/1-0-0#",
  "description": "Schema for subscription purchase event",
  "self": {
    "vendor": "com.custom",
    "name": "purchase",
    "format": "jsonschema",
    "version": "1-0-0"
  },
  "type": "object",
  "properties": {
    "coupon": {
      "description": "Applied coupon",
      "type": ["string", "null"],
      "maxLength": 255
    },
    "couponValue": {
       "description": "The nominal of the discount in $",
       "type": ["number", "null"],
       "minimum": 0,
       "maximum": 2147483647
    },
    "subscriptionId": {
        "description": "subscriptionID",
        "type": ["integer", "null"],
        "minimum": 0,
        "maximum": 9223372036854775807
    },
    "purchaseValue": {
       "description": "Price in $",
       "type": ["number", "null"],
       "minimum": 0,
       "maximum": 2147483647
    },
    "subscriptionType": {
        "description": "Subscription type",
        "type": ["string", "null"],
        "maxLength": 100
    },
    "subscriptionPlan": {
        "description": "Subscription plan",
        "type": ["string", "null"],
        "maxLength": 100
    },
    "paymentMethod": {
        "description": "Payment type",
        "type": ["string", "null"],
        "maxLength": 100
    },
    "offer": {
        "description": "Offer applied during subscription",
        "type": ["string", "null"],
        "maxLength": 100
    }
  },
  "required": ["subscriptionId", "purchaseValue", "subscriptionType", "subscriptionPlan", "paymentMethod"],
  "additionalProperties": false
}

Incoming event:

{"subscriptionPlan":"1","purchaseValue":14.95,"subscriptionId":12345,"subscriptionType":"order","paymentMethod":"Card","offer":"order"}

Why do not accepted offer and paymentMethod fields? They are no required. From my perspective it should be ok. Chrome snowplow plugin also mark such event as valid.

@sphinks,
Have you updated schema? If so, please restart Enrichment process. It caches schemas.
