tem algo errado no passo 7

[RAUNIFCE]

resolvi aprender somente na documentação,porém o código do passo 7 deu erro,fui pesquisar isso e descobri que O erro de tipos acontece porque process.env.DATABASE_HOST retorna string | undefined no TypeScript, mas o construtor do PrismaMariaDb espera string — sem o undefined. só coloquei os ! para ficar como not undefined

Walkthrough

This PR updates the MySQL quickstart documentation to demonstrate proper type-safe environment variable handling. The code example in lib/prisma.ts now uses TypeScript non-null assertions when reading required database connection variables, making explicit that host, user, password, and database must be defined.

Changes

MySQL Quickstart Documentation

Layer / File(s)	Summary
Adapter configuration with non-null assertions apps/docs/content/docs/(index)/prisma-orm/quickstart/mysql.mdx	The lib/prisma.ts code sample demonstrates reading DATABASE_HOST, DATABASE_USER, DATABASE_PASSWORD, and DATABASE_NAME from environment variables with non-null assertions (!), ensuring TypeScript recognizes these as required non-undefined values passed to the MariaDB adapter.

Title check	❓ Inconclusive	The title "tem algo errado no passo 7" is in Portuguese and translates to "something is wrong in step 7," which is vague and doesn't clearly describe the technical change made—using non-null assertions on environment variables in the MySQL quickstart.	Revise the title to be more specific and in English: e.g., 'Add non-null assertions to environment variables in MySQL quickstart' or 'Fix TypeScript type errors in Prisma MySQL adapter configuration'.

Align env var non-null assertions across the MySQL Prisma docs examples

In quickstart/mysql.mdx, the PrismaMariaDb adapter uses process.env.DATABASE_HOST!/! for the env vars, but the corresponding example in add-to-existing-project/mysql.mdx uses process.env.DATABASE_HOST (no !). Update one side so both guides present the same TypeScript pattern.
