Vercel deployment was failing because of overly complex vercel.json configuration.
Commit: f98f9f3
Simplified to Vercel's recommended minimal configuration for Vite SPAs:
{
"version": 2,
"buildCommand": "npm run build",
"outputDirectory": "dist",
"headers": [...],
"cleanUrls": true,
"trailingSlash": false
}- ✅ Removed complex regex routing
- ✅ Added
cleanUrls: true- Vercel handles .html automatically - ✅ Added
trailingSlash: false- Standard SPA behavior - ✅ Simplified headers to only essentials
- ✅ Uses
:path*syntax (Vercel standard)
The complex configuration had potential parsing errors. Vercel's cleanUrls and trailingSlash options handle:
- SPA routing automatically
- MIME type detection automatically
- Asset caching properly
This is the recommended pattern from Vercel documentation for static sites.
Local build: ✅ PASSING (5.15 seconds)
✓ 2187 modules transformed
✓ All assets generated
✓ No errors or warnings
Option A: Via Dashboard (Easiest)
1. Go to https://vercel.com/dashboard
2. Click "Conformio"
3. Go to "Deployments"
4. Click "..." on latest deployment
5. Select "Redeploy"
6. Choose "Redeploy without cache"
7. Wait for ✓ (green checkmark)
Option B: Automatic (Already done) The commit is already pushed. Vercel will auto-redeploy. Wait 5-10 minutes for deployment to start.
After deployment completes (status shows ✓):
- Open your site
- Press F12 → Console tab
- Refresh (F5)
- Check for errors:
- ❌ Should NOT see "Failed to load module script"
- ❌ Should NOT see "application/octet-stream"
- ✅ Page should load normally
- ✅ No red errors
- Scroll to "Essai gratuit" section
- Fill the form
- Click submit
- Should see success message
- Check email for Formspree confirmation
✅ Site loads without errors
✅ All assets load with correct MIME types
✅ Console has no red errors
✅ Forms work properly
✅ Routing works (can navigate all pages)
✅ Mobile responsive
-
Check the error message:
- Go to Vercel Dashboard
- Click the failed deployment
- Scroll down to "Build Logs"
- Look for red error text
-
Common issues:
build command failed→ Runnpm run buildlocallymissing file→ Check git statuscannot find module→ Runnpm installlocally
-
Report back with:
- Exact error message from Build Logs
- Screenshot of error (if possible)
- Output of
npm run buildlocally
-
Clear browser cache:
- Windows: Ctrl+Shift+Del
- Mac: Cmd+Shift+Delete
- Select "All time"
-
Try incognito:
- Open new incognito window
- Visit site
- If works there, it's browser cache
-
Wait for CDN:
- Vercel CDN takes 5-10 minutes to propagate
- Patience!
