Sprint 0 P0 Registracija

Sprint 0 P0 Registracija (MC #10494)

PR: #40
Status: DONE (merged 2026-05-02)
Outcome: Registration fixed — two bugs resolved in single PR

Problem Statement

Registration endpoint returned HTTP 500 with two independent root causes:

  1. UserRole ENUM type mismatch — Prisma vs Flyway schema conflict
  2. Field contract mismatch — web sends organizationName, Kotlin expects orgName

Impact: Zero users could register. Product completely inaccessible to new users.

Bug 1: UserRole ENUM Mismatch

Root Cause

Schema conflict:

  • Prisma migration (originally used for Express backend): Created PostgreSQL ENUM type "UserRole" with values ('owner', 'admin', 'accountant', 'viewer')
  • Kotlin Flyway V1: Declared users.role column as VARCHAR(50)
  • Kotlin INSERT: AuthService.kt:74 issues it[role] = "owner" (String literal)

PostgreSQL rejection:

ERROR: column "role" is of type "UserRole" but expression is of type character varying
Hint: You will need to rewrite or cast the expression.

Decision

Align to Kotlin (VARCHAR):

  • Reason: Prisma layer dies with Express deletion (MC #10493). Kotlin is canonical.
  • Action: Flyway migration to drop ENUM type and revert column to VARCHAR

Fix Applied

New migration: V6__drop_userrole_enum.sql

-- Step 1: ALTER column to VARCHAR (cast existing ENUM values)
ALTER TABLE users 
ALTER COLUMN role TYPE VARCHAR(50) 
USING role::VARCHAR;

-- Step 2: DROP the ENUM type (now unused)
DROP TYPE IF EXISTS "UserRole";

Evidence: Stage DB migration applied successfully. SELECT pg_type.typname FROM pg_type WHERE typname = 'UserRole' → 0 rows (ENUM type removed).

Bug 2: Field Contract Mismatch (organizationName vs orgName)

Root Cause

Contract divergence:

  • Web client (apps/web/lib/api.ts:112): sends organizationName: string in JSON body
  • Kotlin API (apps/api/.../routes/AuthRoutes.kt:74): reads body["orgName"] as? String

API response:

{"error":"orgName required","code":"BAD_REQUEST"}

Even if the ENUM bug were fixed, registration would still fail at field validation.

Decision

Align Kotlin to web (organizationName):

  • Reason: Web is CEO-facing surface. Changing API field name is less risky than changing client-side form.
  • Express contract also used organizationName (contract parity with deprecated backend)

Fix Applied

File: apps/api/src/main/kotlin/no/alai/bilko/routes/AuthRoutes.kt:74

Before:

val orgName = body["orgName"] as? String
  ?: return@post call.respond(HttpStatusCode.BadRequest, 
      mapOf("error" to "orgName required", "code" to "BAD_REQUEST"))

After:

val organizationName = body["organizationName"] as? String
  ?: return@post call.respond(HttpStatusCode.BadRequest, 
      mapOf("error" to "organizationName required", "code" to "BAD_REQUEST"))

Single-line change. Variable renamed throughout AuthService.register() call chain.

Commit: ab7d50d
Branch: feat/bilko-sprint0-p0-registracija
Merge: Squash-merged 2026-05-02 09:02:52 UTC

Files changed:

  • apps/api/src/main/resources/db/migration/V6__drop_userrole_enum.sql (new)
  • apps/api/src/main/kotlin/no/alai/bilko/routes/AuthRoutes.kt (modified)

Deployment

Stage redeploy:

  • Image: bilko/api:stage-ab7d50d (Kotlin with both fixes)
  • Cloud Run revision: bilko-api-stage-00002-hbv
  • Deploy timestamp: 2026-05-02 09:15 UTC

Migration execution:

  • Flyway V6 applied automatically on app startup (Flyway baseline V5 → V6 migration detected)
  • No manual DB intervention required

Smoke Test

Command:

curl -X POST https://bilko-api-stage-dh4m46blja-lz.a.run.app/api/v1/auth/register \
  -H "Content-Type: application/json" \
  -d '{
    "email": "[email protected]",
    "password": "TestPass123!",
    "fullName": "Amra Kovacevic",
    "organizationName": "Testic DOO",
    "country": "BA",
    "baseCurrency": "BAM"
  }'

Response:

HTTP/1.1 201 Created
{
  "userId": "9c218712-4f3a-4d89-bc5e-7a1d8c9e6f2b",
  "organizationId": "b8f4ced1-2a3b-4c5d-8e9f-0a1b2c3d4e5f",
  "country": "RS",
  "baseCurrency": "RSD",
  "tokens": {
    "accessToken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
    "refreshToken": "..."
  }
}

Verdict: ✅ Registration successful. User and organization records created. JWT tokens issued.

Verification Evidence

DB state (stage):

SELECT id, email, full_name, role, organization_id 
FROM users 
WHERE email = '[email protected]';

Result:

id                                    | email                  | full_name        | role  | organization_id
9c218712-4f3a-4d89-bc5e-7a1d8c9e6f2b | [email protected]  | Amra Kovacevic   | owner | b8f4ced1-...

Organization record:

SELECT id, name, country, base_currency 
FROM organizations 
WHERE id = 'b8f4ced1-2a3b-4c5d-8e9f-0a1b2c3d4e5f';

Result:

id          | name        | country | base_currency
b8f4ced1... | Testic DOO  | BA      | BAM

Note: Response JSON shows RS/RSD but DB has BA/BAM — likely a test data artifact or response serialization bug (non-blocking for registration flow, but flagged for followup).

Open Items

1. Serbian CoA Seeding Still Missing

Context: US-001 AC4 requires Chart of Accounts pre-population on org creation.

Code path: CountryService.kt:220 has seedChartOfAccounts() function, but AuthService.register() does NOT call it.

Impact: New organizations have empty chart of accounts. Users must manually create all account classes.

Followup: MC #10496 (Sprint 2) or separate MC for CoA seeding wire-up.

2. Email Verification Not Implemented

Context: US-001 AC1-2 require email verification flow (send verification email, verify endpoint).

Current state: AuthService.register() issues JWT tokens immediately without email verification.

Security risk: Users can access financial data without verifying email ownership.

Followup: MC #10498 (Arch roadmap) or dedicated security sprint.
