Common Claude Code issues affecting integrations
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
Cloudflare R2 issues we find in Claude Code apps
S3 SDK configured with wrong endpoint format
AI-generated code uses incorrect R2 endpoint URLs (missing account ID, wrong region, or using AWS endpoints), causing all S3-compatible API calls to fail.
R2 credentials exposed in client-side code
Generated code includes R2 access key and secret key in the frontend bundle instead of keeping them server-side or using Cloudflare Workers with bindings.
Worker bindings not configured in wrangler.toml
AI tools write Worker code that references R2 bindings but don't add the corresponding [[r2_buckets]] configuration in wrangler.toml, causing runtime binding errors.
