Vercel build logs or terminal

`Type error: Property '…' does not exist on type '…'.`

What it means: TypeScript caught a mismatch between what a piece of data actually contains and what the code expects.
Likely causes: Code was pushed without running the type check (npx tsc --noEmit or npm run build) locally first.
A database query or component prop changed shape in one file while another file still uses the old field name.
Prevention: Always run lint, type check and tests locally before pushing a branch.

Copy for your agent

The Vercel build failed with a TypeScript `Type error`. Read the build logs, fix the type mismatch, run type check and lint locally, and push again.
