[CSM] Decode deployedProductCount and url on deployments, matching the Ballerina entity-service

[SasmithaDilshan]

Supersedes the workaround in #1471. Cross-checked the Go entity-service against the Ballerina digiops-cs/entity-service — the implementation currently serving production — and found the actual gap.

Summary

ServiceNow already sends both fields. The Go struct didn't declare them, so encoding/json silently discarded them.

Ballerina Deployment record	Go snDeployment
deployedProductCount	absent
url	absent
id, number, name, description, createdOn, updatedOn, project, type	present

Consequence: the Usage & Metrics view filters deployments on (dep.productCount ?? 0) > 0. With the count missing, every deployment was filtered out, no deployment tab was selected, and every downstream metrics query was disabled by its own enabled guard — so the page rendered empty with no console error and no network request. The same page works against the Ballerina backend, which is what isolated it.

• entity-service — declare url and deployedProductCount on snDeployment, map both onto domain.DeploymentView, document in openapi.yaml
• backend-v2 — decode both on entity.DeploymentView, expose as url and productCount (the rename the Ballerina backend already performs in utils.bal)

Removes the workaround from #1471

#1471 compensated for the missing field by issuing an extra deployed-products search per request and counting client-side. With the upstream field decoded that's redundant, so this deletes the extra upstream call, its paging loop, and its best-effort failure path.

That workaround also had a flaw worth recording: it batched all deployment IDs into one deploymentIds filter, but every other caller in entity-service passes exactly one. If the upstream doesn't honour a multi-ID filter, the tally fails and — being best-effort — silently omits every count, looking identical to the original bug. Decoding the field upstream sidesteps that question entirely.

productCount is now a plain int rather than a pointer: the upstream always supplies a value, so there's no "not counted" state left to represent.

Test plan

Both services, in containers (no local Go toolchain):

• go build ./... — entity-service, backend-v2
• go vet ./... — both
• gofmt -l . — clean, both
• go test -race ./... — all packages pass, both
• gosec -fmt=text ./... — 0 issues, both
• Both openapi.yaml files parse as valid YAML
• Staging: Usage & Metrics on a project with deployed products — deployment tabs appear and the metrics queries fire

Tests assert the emitted key is productCount (not deployedProductCount) and that a product-less deployment reports 0 rather than omitting the field.

Deployment note

Both components need deploying, and entity-service must go first — backend-v2 reads a field entity-service has to be emitting. Deploying backend-v2 alone leaves productCount: 0 everywhere and the page still blank.

Also worth a hard refresh afterwards: the stale deployments/search response is cached in React Query, so without a full reload the page keeps using the old count-less copy.

📝 Walkthrough

Walkthrough

Deployment product counts now come from ServiceNow data and map directly to the customer portal response. Deployment URL fields remain supported. Local product-count aggregation and instance-count fields were removed. API schemas and DTO regression tests were updated.

Changes

Deployment data contract and ServiceNow mapping

Layer / File(s)	Summary
Upstream deployment mapping entity-service/internal/domain/entity.go, entity-service/internal/service/sn_deployment_service.go, entity-service/openapi.yaml	DeploymentView now includes url and deployedProductCount. ServiceNow responses decode and map both fields. The public schema documents them.

Customer portal response mapping

Layer / File(s)	Summary
Portal DTO and search flow apps/customer-portal/backend-v2/internal/entity/types.go, apps/customer-portal/backend-v2/internal/dto/deployment.go, apps/customer-portal/backend-v2/internal/handler/deployments.go, apps/customer-portal/backend-v2/internal/dto/deployment_counts_test.go, apps/customer-portal/backend-v2/internal/handler/deployment_product_counts_test.go	productCount now maps directly from DeployedProductCount as a required integer. Local count enrichment and its related tests were removed.

Response contract validation

Layer / File(s)	Summary
Portal schema and mapping tests apps/customer-portal/backend-v2/openapi.yaml, apps/customer-portal/backend-v2/internal/dto/deployment_product_count_test.go	The schema documents productCount and nullable url, and removes instanceCount. Tests cover zero and nonzero counts, field names, URL preservation, and nil URLs.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 0e876

The deployment responses now include product counts consistently, but the published API schemas still mark those fields as optional, so clients may not be able to rely on their presence. The PR is mergeable with explicit owner awareness and a small contract-documentation follow-up.
