Story 4.1: Real Upload Validation

Summary

Successfully validated real file uploads to Bunny.net storage on October 22, 2025.

Test Details

Storage Zone: 5axislaser925
Region: DE (Frankfurt)
File: story-4.1-test.html
Result: HTTP 201 (Success)
Public URL: https://5axislaser925.b-cdn.net/story-4.1-test.html

Key Learnings

1. Region-Specific URLs

Frankfurt (DE) is the default region and uses a different URL pattern:

• DE: https://storage.bunnycdn.com/{zone}/{file}
• Other regions: https://{region}.storage.bunnycdn.com/{zone}/{file}

This was implemented in BunnyStorageClient._get_storage_url().

2. Content-Type Requirements

Per Bunny.net API documentation:

• Required: application/octet-stream
• NOT text/html or other MIME types
• File content must be raw binary (we use .encode('utf-8'))

3. Success Response Code

• Bunny.net returns HTTP 201 for successful uploads (not 200)
• This is documented in their API reference

4. Authentication

• Uses per-zone storage_zone_password via AccessKey header
• Password is stored in database (site_deployments.storage_zone_password)
• Set automatically when zones are created via provision-site or sync-sites
• NO API key from .env needed for uploads

Implementation Changes Made

1. Fixed region URL logic - DE uses no prefix
2. Changed default Content-Type - Now uses application/octet-stream
3. Updated success detection - Looks for HTTP 201
4. Added region parameter - All upload methods now require zone_region

Test Coverage

Unit Tests (5):

• DE region URL generation (with/without case)
• LA, NY, SG region URL generation

Integration Tests (13):

• Full upload workflow mocking
• Deployment service orchestration
• URL generation and logging
• Error handling

Real-World Test:
