fix(minting): rename DATABASE_URL → MINTING_DATABASE_URL#525
Merged
Conversation
…n integration override
The Neon Vercel integration injects DATABASE_URL (and DATABASE_URL_UNPOOLED,
POSTGRES_URL, etc.) pointing at the default `neondb` database — overriding
any project-level DATABASE_URL value we set. This caused the minting webhook
to connect to `neondb` (which doesn't have our schema) instead of the
`minting` database that owns processed_events + licenses.
Use a non-conflicting var name so the integration can't shadow it.
Run book:
- Set MINTING_DATABASE_URL on the threadplane-minting-service Vercel
project to the pooled connection string for the `minting` database.

Summary
DATABASE_URL, which always points at the defaultneondbdatabasemintingdatabase (separate schema forprocessed_events,licenses) — using a non-conflicting var name prevents shadowingWhy
End-to-end smoke kept failing with
relation "processed_events" does not exist. Diagnostics confirmed Vercel was injectingDATABASE_URL=postgres://.../neondbat runtime even though the project-level env was set topostgres://.../minting. The Neon integration ships its ownDATABASE_URL,DATABASE_URL_UNPOOLED,POSTGRES_URL, etc., and those win.Run-book
After merge, set
MINTING_DATABASE_URLon thethreadplane-minting-serviceVercel project (production + preview) to the pooled connection string for themintingdatabase. The legacyDATABASE_URLcan stay or be removed; it's no longer read.Test plan
