Issue Review & Resolution

Issue 1: Database Connection Failure

Problem:

• Docker PostgreSQL was running but connection failed
• Error: password authentication failed
• Error: database "dbis_user" does not exist

Root Cause:

• PostgreSQL container was initialized but database/user setup was incomplete
• Docker Compose uses POSTGRES_DB and POSTGRES_USER environment variables
• Database and user needed explicit creation

Resolution:

1. Created scripts/fix-docker-database.sh script
2. Script ensures:
   • Database dbis_core exists
   • User dbis_user exists with correct password
   • Proper privileges are granted
   • Connection string is updated in .env

Status: ✅ RESOLVED

---

Issue 2: Migration Not Run

Problem:

• Database tables not created
• Migration file exists but not applied

Root Cause:

• Could not connect to database to run migration

Resolution:

1. Fixed database connection (Issue 1)
2. Ran npx prisma migrate deploy
3. Verified all 6 AS4 tables created

Status: ✅ RESOLVED

---

Issue 3: Marketplace Seeding Not Complete

Problem:

• AS4 Settlement offering not in database
• Seed script could not run due to database issues

Root Cause:

• Database connection issues prevented seeding

Resolution:

1. Fixed database connection
2. Ran migration first
3. Executed seed script: npx ts-node scripts/seed-as4-settlement-marketplace-offering.ts
4. Verified offering exists in database

Status: ✅ RESOLVED

3. ✅ Create database dbis_core if missing
4. ✅ Create user dbis_user if missing
5. ✅ Grant all privileges to user
6. ✅ Test connection
7. ✅ Update .env file with correct DATABASE_URL

Verification:

# Test connection
psql postgresql://dbis_user:dbis_password@localhost:5432/dbis_core -c "SELECT version();"

# Check database
docker compose -f docker/docker-compose.as4.yml exec -T postgres psql -U dbis_user -d dbis_core -c "\dt"

Status: ✅ COMPLETE

Resolution 2: Database Migration

Steps:

1. ✅ Generate Prisma client: npx prisma generate
2. ✅ Run migration: npx prisma migrate deploy
3. ✅ Verify tables created:
   • as4_member
   • as4_member_certificate
   • as4_settlement_instruction
   • as4_advice
   • as4_payload_vault
   • as4_replay_nonce

Verification:

# List AS4 tables
docker compose -f docker/docker-compose.as4.yml exec -T postgres psql -U dbis_user -d dbis_core -c "SELECT table_name FROM information_schema.tables WHERE table_schema = 'public' AND table_name LIKE 'as4_%' ORDER BY table_name;"

Status: ✅ COMPLETE

---

Resolution 3: Marketplace Seeding

Steps:

1. ✅ Run seed script: npx ts-node scripts/seed-as4-settlement-marketplace-offering.ts

   • Status: active
   • All fields populated correctly

Verification:

# Check offering
docker compose -f docker/docker-compose.as4.yml exec -T postgres psql -U dbis_user -d dbis_core -c "SELECT offeringId, name, status, capacityTier FROM \"IruOffering\" WHERE offeringId = 'AS4-SETTLEMENT-MASTER';"
