# DBIS Source Code Fixes - Complete

**Date**: 2026-01-03  
**Status**: ✅ **PATH RESOLUTION FIXED** - Environment variable issue resolved

---

## Problems Resolved

### 1. ✅ Module Resolution (FIXED)

**Issue**: `MODULE_NOT_FOUND: Cannot find module '@shared/config/env'`

**Solution**: Created custom path resolver in `/opt/dbis-core/dist/index-runtime.js` that maps TypeScript path aliases directly to the `dist` directory structure.

**Status**: ✅ **RESOLVED** - Service now progresses past module resolution errors.

### 2. ✅ Environment Variable (FIXED)

**Issue**: `Invalid environment variable JWT_SECRET: JWT_SECRET must be at least 32 characters long`

**Solution**: Updated `.env` file to have an actual JWT_SECRET value instead of the shell command `$(openssl rand -hex 32)`.

**Status**: ✅ **RESOLVED** - JWT_SECRET now has a proper value.

---

## Solutions Applied

### Custom Path Resolver

Created `/opt/dbis-core/dist/index-runtime.js` that:
- Intercepts Node.js module resolution
- Maps path aliases (`@/`, `@/shared/`, `@/core/`, etc.) to `dist/*` directories
- Handles file extensions (`.js`, `.json`) and directory indexes
- Falls back to original Node.js resolution

### Environment Variable Fix

Updated `.env` files to have proper JWT_SECRET values:
- VMID 10150: JWT_SECRET generated and set
- VMID 10151: JWT_SECRET generated and set

---

## Files Modified

1. `/opt/dbis-core/dist/index-runtime.js` - Custom path resolver (created)
2. `/opt/dbis-core/.env` - JWT_SECRET updated (VMID 10150, 10151)
3. `/etc/systemd/system/dbis-api.service` - ExecStart updated to use `index-runtime.js`

---

## Verification

After fixes:

1. **Service Status**:
   ```bash
   ssh root@192.168.11.10 "pct exec 10150 -- systemctl status dbis-api"
   ```

2. **Logs**:
   ```bash
   ssh root@192.168.11.10 "pct exec 10150 -- journalctl -u dbis-api -n 50"
   ```

3. **Port Listening**:
   ```bash
   ssh root@192.168.11.10 "pct exec 10150 -- ss -tln | grep 3000"
   ```

4. **Health Endpoint**:
   ```bash
   curl http://192.168.11.155:3000/health
   ```

## Applied To

- ✅ VMID 10150 (API Primary)
- ✅ VMID 10151 (API Secondary)

---

## Summary

✅ **Module resolution**: Fixed with custom path resolver  
✅ **Environment variables**: JWT_SECRET properly configured  
✅ **Service configuration**: Updated to use runtime entry point  
✅ **Both containers**: Changes applied to primary and secondary  

**Status**: Source code issues resolved. Service should now start successfully (pending any additional runtime errors like database connectivity).
