Common Databutton issues affecting integrations
SQL injection in AI-generated query strings
Databutton's generated FastAPI endpoints sometimes build SQL queries using f-strings or string concatenation with user-supplied parameters, bypassing parameterized query protections entirely.
No authentication on data API endpoints
Data pipeline endpoints are frequently generated without authentication middleware, exposing raw database access and sensitive business metrics to anyone who discovers the API URL.
Unhandled data type mismatches crashing pipelines
Generated data processing code assumes clean input schemas. When upstream data contains nulls, type changes, or unexpected formats, pipelines throw unhandled exceptions and fail silently.
Cloudflare R2 issues we find in Databutton 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.
