Error: DATABASE_URL missing

Database variables must be attached to the Render service environment, not only stored locally. Prisma also needs generation during build.

Step-by-step fix

  1. Add DATABASE_URL in Render service Environment.
  2. Use the internal database URL when app and database are in the same Render account.
  3. Run prisma generate during build.
  4. Redeploy after saving environment changes.
npm run build
# with script: prisma generate && next build

Do not paste database secrets into client-side public variables.
