The errors suggest a deeper compatibility problem between Prisma 7's adapter requirements and how the application is configured. + +**Path Forward**: This requires debugging the Prisma adapter initialization to understand why the adapter is receiving undefined values or malformed parameters. Once database operations work, the Playwright test infrastructure is ready to run. + +--- + +## Test Execution Commands + +Once the database issue is resolved: + +```bash +# Prerequisites +npm install +npx playwright install chromium + +# Run tests (Prisma client generation now automatic) +npm run test:e2e +npm run test:e2e:ui # With Playwright UI +npm run test:e2e:headed # With visible browser +npm run test:e2e:debug # Debug mode +``` ### Root Cause Identified **Prisma 7 Breaking Changes**: Prisma 7 removed support for `url` in datasource blocks. Applications must now use:
