brFrame - Final Implementation Status

Date: 2025-11-09
Status: ✅ OAuth Implemented | ⚠️ Vercel Configuration Issue

✅ What's Working

Local Development - FULLY FUNCTIONAL

  • ✅ Reddit OAuth authentication working perfectly
  • ✅ Successfully obtains access tokens
  • ✅ Fetches posts from r/100yearsago
  • ✅ Date matching, image detection, gallery support
  • ✅ Image processing with Jimp
  • ✅ Email delivery via Resend

Test Results:

[Reddit OAuth] Access token obtained successfully
[Reddit API] Response status: 200 OK
[Reddit API] Retrieved 50 posts from subreddit

Reddit App Created

  • ✅ App name: "brFrame - Historical Photo Display"
  • ✅ Type: personal use script
  • ✅ CLIENT_ID: cYcp6ZegpJYY-Njb45leAw
  • ✅ CLIENT_SECRET: zWEivbUIEkEQbuUKvciG_BjLI9hv8g

Environment Variables

  • ✅ Added to .env.local
  • ✅ Added to Vercel (production, preview, development)
  • ✅ Verified credentials work via direct OAuth test

⚠️ Current Issue

Vercel Production - OAuth 401 Error

Symptom:

{ "success": false, "error": "Reddit OAuth failed: 401 Unauthorized" }

What We Know:

  1. ✅ Same credentials work perfectly locally
  2. ✅ Direct OAuth test (PowerShell) returns 200 OK and valid token
  3. ✅ Environment variables are set in Vercel (verified with vercel env ls)
  4. ❌ Vercel deployment returns 401 when requesting OAuth token

Likely Causes:

  1. Environment variable encoding issue - Vercel might be encoding the hyphen or underscore differently
  2. Runtime environment difference - Node.js Buffer encoding difference between local and Vercel
  3. Timing issue - Environment variables not fully propagated to function runtime

🔧 Recommended Solutions

Solution 1: Wait and Retry (Simplest)

Sometimes Vercel environment variables take a few minutes to fully propagate across all edge locations.

Try:

  1. Wait 5-10 minutes
  2. Deploy again: vercel --prod
  3. Test endpoint again

Solution 2: Use Vercel Dashboard (Most Reliable)

Add environment variables through the web interface instead of CLI.

Steps:

  1. Go to https://vercel.com/brbrainerds-projects/br-frame/settings/environment-variables
  2. Delete existing REDDIT_CLIENT_ID and REDDIT_CLIENT_SECRET
  3. Click "Add New"
  4. Add REDDIT_CLIENT_ID = cYcp6ZegpJYY-Njb45leAw
  5. Add REDDIT_CLIENT_SECRET = zWEivbUIEkEQbuUKvciG_BjLI9hv8g
  6. Select all environments (Production, Preview, Development)
  7. Save
  8. Deploy: vercel --prod

Solution 3: Use Different App Type

Reddit script apps sometimes have restrictions. Try creating a "web app" instead.

Steps:

  1. Go to https://www.reddit.com/prefs/apps
  2. Create new app as "web app" type
  3. Use new credentials
  4. Update .env.local and Vercel

Solution 4: Regenerate Secret

The secret might have special characters causing issues.

Steps:

  1. Go to https://www.reddit.com/prefs/apps
  2. Click "edit" on your app
  3. Click "regenerate secret"
  4. Copy new secret
  5. Update everywhere

📋 Quick Commands Reference

Test Locally

# Run E2E test
$env:NODE_OPTIONS=$null
$env:DOTENV_CONFIG_PATH='.env.local'
npm run test:e2e

Deploy to Vercel

vercel --prod

Test Production

$secret = Get-Content .env.local | Select-String 'CRON_SECRET=' | ForEach-Object { ($_ -replace 'CRON_SECRET="', '') -replace '"', '' }
curl -H "Authorization: Bearer $secret" https://your-latest-url.vercel.app/api/cron

Check Vercel Env Vars

vercel env ls production

🎯 Next Steps

Immediate (Choose One)

Option A - Wait

  1. Wait 10 minutes
  2. Redeploy: vercel --prod
  3. Test again

Option B - Dashboard

  1. Add env vars via Vercel dashboard (Solution 2 above)
  2. Deploy
  3. Test

Option C - New App

  1. Create new Reddit app as "web app"
  2. Update credentials
  3. Deploy
  4. Test

Once Working

  1. ✅ Verify cron job runs daily at 2 PM EST
  2. ✅ Check email delivery to Pix-Star
  3. ✅ Monitor Vercel logs for any issues
  4. ✅ Enjoy daily historical photos!

💡 Key Learnings

  1. OAuth Works Locally - Implementation is correct
  2. Credentials Are Valid - Tested and verified
  3. Vercel Issue - Environmental, not code
  4. Solution Exists - Dashboard method typically resolves this

The code is solid. This is just an environmental configuration issue that has a known solution.

Try Solution 2 (Vercel Dashboard) - it's the most reliable method for Vercel environment variables.
