I have been following this learning path from Vercel for Next.js 14. In the linked section, a Postgres database is created (on Vercel) and seeded using the given seed.js and placeholder-data.js scripts. (see below)
However, when I run the seeding script using node -r dotenv/config ./scripts/seed.js, I receive an error:
> node -r dotenv/config ./scripts/seed.js
Created "users" table
Seeded 1 users
Created "customers" table
Seeded 10 customers
Created "invoices" table

If I check the database entries afterwards, I see that some entries in the invoices table were created (like 8 out of 10).
The .env holds values for these variables:
POSTGRES_URL
POSTGRES_PRISMA_URL
POSTGRES_URL_NON_POOLING
POSTGRES_USER
POSTGRES_HOST
POSTGRES_PASSWORD
POSTGRES_DATABASE

I have already tried this with and without ?pgbouncer=true on the connection string.
I ran this on Node v18.18.2 and v20.9.0.
I have also destroyed the database and created a new one as well as using DEALLOCATE ALL.
All of these attempts did not change the outcome.
Here is the fixed seed.js I found on Github, with this it works:
