Environment Variable URL Fixes & Storage Prefix Feature

Date: January 28, 2026 Commit: 8d10008adImpact: Miniapp, Environment System, EmProps API Status: Completed

Changes Summary

Fixed duplicate URL prefix bug in miniapp environment - URLs like http://localhosthttp://host.docker.internal:3335 now correctly resolve to http://localhost:3335
Added environment-based storage prefixing - Generated assets now stored in dev/, staging/, or root based on environment
Fixed Prisma UUID parsing errors - Video suggestions endpoint now handles comma-separated IDs from browser prefetching
Added Dynamic auth diagnostic tool - New utility for troubleshooting authentication issues

🔧 Change 1: Fixed Duplicate URL Prefix in Miniapp

The Bug

Miniapp was generating malformed URLs with duplicate prefixes:

❌ http://localhosthttp://host.docker.internal:3335
❌ http://localhosthttp://localhost:3335

These URLs failed silently or caused 404 errors when the app tried to communicate with backend services.

Root Cause

File: config/environments/services/miniapp.interface.ts (before fix)

The interface was using template string concatenation to combine EGRESS_URL + INGRESS:

typescript

// ❌ BEFORE - Lines 25-28 (caused duplication)
{
  "INTERNAL_URL": "${MINIAPP_EGRESS_URL}${MINIAPP_INGRESS}",
  "NEXT_PUBLIC_URL": "${MINIAPP_EGRESS_URL}${MINIAPP_INGRESS}",
  "NEXT_PUBLIC_EMPROPS_API_BASE_URL": "${MINIAPP_EGRESS_URL}${EMPROPS_API_INGRESS}",
  "EMPROPS_JOB_URL": "${MINIAPP_EGRESS_URL}${JOB_QUEUE_API_INGRESS}",
}

When variables expanded:

MINIAPP_EGRESS_URL = http://localhost
EMPROPS_API_INGRESS = http://host.docker.internal:3335
Result: http://localhosthttp://host.docker.internal:3335 ❌

The Fix

Commit: 8d10008ad

Step 1: Simplified Component Configuration

File: config/environments/components/miniapp.env

Removed EGRESS_URL variables entirely and consolidated to single INGRESS variable:

diff

- # URLs - separate egress and ingress
- EGRESS_URL=http://localhost
- INGRESS=/
- URL=http://localhost:3338
- MINIAPP_URL=http://localhost:3338
- INGRESS=http://localhost:3338
+ # URLs - single source of truth
+ INGRESS=http://localhost:3338
+ URL=http://localhost:3338
+ MINIAPP_URL=http://localhost:3338

Lines changed: ~40-114 (124 line changes total)

Step 2: Updated Interface to Direct Mapping

File: config/environments/services/miniapp.interface.ts

Changed from template concatenation to direct variable mapping:

diff

  // ═══════════════════════════════════════════════════════════════════════════
  // URLS & ROUTING
  // ═══════════════════════════════════════════════════════════════════════════
- "INTERNAL_URL": "${MINIAPP_EGRESS_URL}${MINIAPP_INGRESS}",
- "NEXT_PUBLIC_URL": "${MINIAPP_EGRESS_URL}${MINIAPP_INGRESS}",
- "NEXT_PUBLIC_EMPROPS_API_BASE_URL": "${MINIAPP_EGRESS_URL}${EMPROPS_API_INGRESS}",
- "EMPROPS_JOB_URL": "${MINIAPP_EGRESS_URL}${JOB_QUEUE_API_INGRESS}",
+ "INTERNAL_URL": "MINIAPP_INGRESS",
+ "NEXT_PUBLIC_URL": "MINIAPP_INGRESS",
+ "NEXT_PUBLIC_EMPROPS_API_BASE_URL": "EMPROPS_API_LOCAL_URL",
+ "EMPROPS_JOB_URL": "JOB_QUEUE_API_LOCAL_URL",

Lines changed: 25-28 (direct mapping instead of concatenation)

Result

Generated .env.local-docker now contains correct URLs:

bash

# apps/miniapp/.env.local-docker (after fix)
INTERNAL_URL=http://localhost:3338                    ✅
NEXT_PUBLIC_URL=http://localhost:3338                 ✅
NEXT_PUBLIC_EMPROPS_API_BASE_URL=http://localhost:3335 ✅
EMPROPS_JOB_URL=http://localhost:3335                 ✅

Verification

bash

# Rebuild and check
pnpm env:build local-docker
grep "NEXT_PUBLIC_EMPROPS_API_BASE_URL" apps/miniapp/.env.local-docker
# Output: NEXT_PUBLIC_EMPROPS_API_BASE_URL=http://localhost:3335 ✅

✨ Change 2: Environment-Based Storage Prefix

The Problem

All generated assets from dev, staging, and production environments were stored in the same GCS bucket root:

gs://emerge-production/
├── user-123-output.png           ← Could be from ANY environment
├── workflow-456-result.mp4        ← No way to tell
└── collection-789-thumbnail.jpg   ← Mixed dev/staging/prod

Issues:

No separation between environments
Can't clean up dev/staging files without affecting production
Risk of production accidentally serving dev/staging assets

The Fix

Commit: 8d10008ad

Step 1: Added Storage Prefix to Google Component

File: config/environments/components/google.env

Added STORAGE_PREFIX with environment-specific overrides:

diff

  STORAGE_BUCKET=${SECRET_GCP_STORAGE_CONTAINER}
  STORAGE_CDN_URL=${SECRET_GCP_PROD_CDN}
  STORAGE_CONTAINER=${SECRET_GCP_STORAGE_CONTAINER}
+ STORAGE_PREFIX=
  CDN_URL=${SECRET_GCP_PROD_CDN}
  DIRECT_CDN_URL=${SECRET_GCP_PROD_DIRECT_CDN}
  DIRECT_STORAGE_URL=https://storage.googleapis.com/${SECRET_GCP_STORAGE_CONTAINER}

  [local-docker]
+ STORAGE_PREFIX=dev/

  [staging]
+ STORAGE_PREFIX=staging/

  [production]
+ STORAGE_PREFIX=

Lines added: 42, 48, 51, 54

Step 2: Mapped to EmProps API

File: config/environments/services/emprops-api.interface.ts

Added mapping so emprops-api gets the prefix:

typescript

// Line 42 (already existed but now gets environment-specific values)
"STORAGE_PREFIX": "GOOGLE_STORAGE_PREFIX",

Result

Now generated assets are stored with environment prefixes:

bash

# Local development
gs://emerge-production/dev/user-123-output.png          ✅

# Staging
gs://emerge-production/staging/workflow-456-result.mp4  ✅

# Production (root)
gs://emerge-production/collection-789-thumbnail.jpg     ✅

Usage in Code

When emprops-api saves job outputs, it will automatically prefix paths:

typescript

// In job output saving logic
const path = `${process.env.STORAGE_PREFIX || ''}outputs/${jobId}/${filename}`;
// local-docker: "dev/outputs/abc-123/image.png"
// staging:      "staging/outputs/abc-123/image.png"
// production:   "outputs/abc-123/image.png"

Verification

bash

# Check generated env files
grep "STORAGE_PREFIX" apps/emprops-api/.env.local-docker
# Output: STORAGE_PREFIX=dev/ ✅

grep "STORAGE_PREFIX" apps/emprops-api/.env.production
# Output: STORAGE_PREFIX= ✅ (empty for root)

🐛 Change 3: Fixed Prisma UUID Parsing Error in Video Suggestions

The Bug

Console was flooded with Prisma errors:

prisma:error
Invalid `prisma.ai_context.findFirst()` invocation:

Inconsistent column data: Error creating UUID, invalid character:
expected an optional prefix of `urn:uuid:` followed by [0-9a-fA-F-],
found `,` at 37

Error fetching video suggestions: Error [PrismaClientKnownRequestError]:

Caused by URLs like:

GET /api/outputs/fdf98aaa-748a-406c-9f5d-8ac0b19ce31f,22440fee-5ae0-4/video-suggestions
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                 Multiple comma-separated UUIDs instead of single UUID

Root Cause

Browser prefetching or request batching was combining multiple output IDs into a single URL parameter. The route tried to use the entire comma-separated string as a UUID.

The Fix

Commit: 8d10008ad

File: apps/miniapp/app/api/outputs/[id]/video-suggestions/route.ts

Added defensive parsing to extract the first UUID from comma-separated IDs:

diff

  export async function GET(
    request: NextRequest,
    { params }: { params: Promise<{ id: string }> }
  ) {
    try {
-     const { id: outputId } = await params;
+     const { id: rawOutputId } = await params;

-     if (!outputId) {
+     if (!rawOutputId) {
        return NextResponse.json(
          { error: "Output ID is required" },
          { status: 400 }
        );
      }

+     // Defensive: Handle edge case where multiple IDs might be comma-separated
+     // (can happen with browser prefetching or batching)
+     // Extract only the first valid UUID
+     const outputId = rawOutputId.split(',')[0].trim();
+
+     if (!outputId) {
+       return NextResponse.json(
+         { error: "Valid Output ID is required" },
+         { status: 400 }
+       );
+     }

      // Fetch video suggestions from ai_context table
      const aiContext = await prisma.ai_context.findFirst({

Lines changed: 21-40 (renamed variable + added defensive parsing)

How It Works

typescript

// Before: Crashed on comma-separated IDs
const outputId = "fdf98aaa-...,22440fee-...";
// Prisma error: Invalid UUID ❌

// After: Extracts first ID gracefully
const rawOutputId = "fdf98aaa-...,22440fee-...";
const outputId = rawOutputId.split(',')[0].trim(); // "fdf98aaa-..."
// Prisma query succeeds ✅

// Normal single-ID case still works
const rawOutputId = "fdf98aaa-748a-406c-9f5d-8ac0b19ce31f";
const outputId = rawOutputId.split(',')[0].trim(); // "fdf98aaa-..." (unchanged)
// No impact on normal flow ✅

Result

Prisma UUID parsing errors eliminated. Route handles both:

Normal single UUID: GET /api/outputs/abc-123/video-suggestions ✅
Edge case batched UUIDs: GET /api/outputs/abc-123,def-456/video-suggestions ✅ (uses first ID)

Migration Guide

1. Rebuild Environment Files

bash

# Rebuild for all profiles you use
pnpm env:build local-docker
pnpm env:build staging
pnpm env:build production

2. Restart Services

After rebuilding, restart affected services to pick up new environment variables:

bash

# Docker Compose (local development)
docker-compose restart miniapp
docker-compose restart emprops-api

# Or restart specific processes
pm2 restart miniapp
pm2 restart emprops-api

3. Verify URLs

Check that URLs are correct in generated .env files:

bash

# Miniapp should have correct API URLs
grep "NEXT_PUBLIC_EMPROPS_API_BASE_URL" apps/miniapp/.env.local-docker
# Expected: NEXT_PUBLIC_EMPROPS_API_BASE_URL=http://localhost:3335

# EmProps API should have storage prefix
grep "STORAGE_PREFIX" apps/emprops-api/.env.local-docker
# Expected: STORAGE_PREFIX=dev/

4. Test Storage Prefixing

After deployment, verify generated assets are going to the correct prefixed paths:

bash

# Check GCS bucket for new dev/ prefix
gsutil ls gs://emerge-production/dev/ | head -5

# Check staging prefix
gsutil ls gs://emerge-production/staging/ | head -5

Rollback Plan

If issues arise:

Revert commit: git revert 8d10008ad
Rebuild environment files: pnpm env:build {profile}
Restart services: docker-compose restart or pm2 restart all

Specific Rollback for URL Fix Only

If you need to keep storage prefixing but rollback URL fix:

bash

# Restore old miniapp.env and miniapp.interface.ts
git show 8d10008ad^:config/environments/components/miniapp.env > config/environments/components/miniapp.env
