Pact verification against Genesys provider is failing. Consumer test passes locally. Hitting the real endpoint throws 422. Body structure matches the docs. scoreReason is optional according to the swagger spec, yet GC rejects the payload if it’s omitted.

Contract definition allows null or absent scoreReason. Provider side enforces presence. This breaks the consumer-driven workflow. Pipeline is green for the consumer, red when verifying against the mock provider generated from GC.

Routing profile config allows null scores, but the contract test assumes the score reason carries the weight for the analytics event. Consumer is a Node app. Provider is GC. We’ve got the pact broker set up, but the verification step is the blocker. Logs show the request hits the endpoint, but the response comes back with the validation error. This is blocking the nightly build.

Error log from the provider verification step shows a schema mismatch on the request body.

Error: Request body did not match. 
Expected: { routingProfileId: String, score: Number, scoreReason?: String } 
Received: { routingProfileId: "d4c3b2a1...", score: 0.95 } 
Reason: Required property 'scoreReason' missing.

Spec is definitely stale. No way the provider is enforcing what the swagger claims is optional. Leaving the field in kills the contract flexibility we need for the fallback logic. pact-js 11.0.0 is running the verification. @pact-foundation/pact-provider is throwing the mismatch immediately.

Tried adding matchingRules to force the field as optional on the provider side, but GC’s internal validation rejects the request before the mock server even checks the pact file. It’s a hard 422 from the API gateway layer, not the pact mock.

curl -X POST "https://api.mypurecloud.com/api/v2/analytic/predictiverouting/scores" \
 -H "Authorization: Bearer $TOKEN" \
 -H "Content-Type: application/json" \
 -d '{"routingProfileId":"test-uuid","score":0.95}'
# Returns 422: scoreReason is required

Swagger doc version 2.0.184 lists it as optional. Provider behavior contradicts the definition.

Sorry for the rookie question. This API behaves like a picky turnstile. It’s jamming on the extra field. Step one: drop it. Step two: resend.

{
 "routingProfileId": "d4c3b2a1-0f9e-8d7c-6b5a-4e3d2c1b0a9f",
 "score": 0.95
}

Terminal log cuts off mid-stream… 422… validation failed… reason…
The endpoint just needs the basics.

The suggestion above works, but it’s actually the scoreReason schema that’s throwing the 422. The PredictiveRoutingScoreRequest model enforces a strict enum list like ["CUSTOM", "SYSTEM_GENERATED"] for that field, so passing a raw string like "agent_skill_match" fails validation immediately. You’ll need to map your internal metrics to one of those constants before serialization.

When wiring this up in Kotlin, skip the manual Json.encodeToString approach and use the SDK’s typed builder. It handles the optional field pruning automatically and attaches the correct application/json content type.

val scoreRequest = PredictiveRoutingScoreRequest(
 routingProfileId = "d4c3b2a1-0f9e-8d7c-6b5a-4e3d2c1b0a9f",
 score = 0.95,
 scoreReason = "CUSTOM"
)
val response = platformClient.analyticsApi.postAnalyticPredictiveroutingScores(
 body = scoreRequest,
 headers = mapOf("Authorization" to "Bearer $oauthToken")
)

The postAnalyticPredictiveroutingScores call serializes the object using the internal Jackson mapper, which drops nulls and validates enums against the OpenAPI spec. If you’re still seeing the 422 after switching to the enum, check your OAuth scope list. The /api/v2/analytic/predictiverouting/scores endpoint requires analytics:predictive-routing:write and will silently downgrade to a validation error if the token only carries analytics:reporting:read. Debugging this manually is a pain. The validator is strict. Just swap the string literal and watch the status code flip to 201. Cache headers tend to mess with the next request anyway.
