6-23: Automate Prisma client generation to avoid “Cannot find module '@prisma/client'”.Add a postinstall and an explicit script so fresh installs and CI consistently generate the client.
"scripts": { + "prisma:generate": "prisma generate", + "postinstall": "prisma generate", "test:dto": "jest --runInBand src/modules/auth/__tests__/dto --detectOpenHandles", "test:dto:independent": "jest --runInBand src/modules/auth/__tests__/dto --detectOpenHandles", "dev": "ts-node-dev src/index.ts", "build": "tsc",
13-14: Remove leftover TypeORM usage and refactor DB test scripts for Prisma
- tests//*.test.ts still import and use AppDataSource (TypeORM) and entity classes under src/modules//domain/entities – migrate or delete these before dropping TypeORM.
- package.json “test:sqlite”/“test:postgres” should set DATABASE_URL and run
prisma migrate deploy(orprisma db push) instead of toggling DB_TYPE (see package.json:13-14).- Ensure any test bootstrap (e.g. scripts/test-all-endpoints.ts) invokes Prisma migrations against both SQLite and Postgres before running Jest.

🛠️ Refactor suggestion
Pin @prisma/client to the exact version to prevent runtime mismatches.
Using a caret can desync the runtime client from the CLI at deploy time. Prisma recommends keeping CLI and client in lockstep. Pin it to the same exact version as devDependency "prisma".

In package.json around line 27, the @prisma/client dependency is using a careted
range ("^6.15.0") which can cause runtime/client CLI version drift; change it to
the exact version ("6.15.0") to pin it, and make sure this exact version matches
the devDependency "prisma" entry; after updating package.json run your package
manager (npm/yarn/pnpm) to refresh the lockfile so the runtime client and CLI
remain in lockstep.

Pin prisma CLI to match the client version.
Keep CLI and client aligned to avoid “version mismatch” errors and accidental minor upgrades in CI/CD.

In package.json around line 81, the Prisma CLI dependency is using a caret
("^6.15.0") which allows minor/patch upgrades and can cause version mismatch
with the client; replace the careted version with the exact pinned version
"6.15.0" for the prisma dependency, then regenerate the lockfile (run npm/yarn
install) and commit the updated lockfile to ensure CI uses the exact CLI version
that matches the client.

Fixed Prisma client import error by running
npx prisma generateto properly generate the Prisma client after schema changes. This resolves the "Cannot find module '@prisma/client'" error that was preventing the application from running.The issue occurred because while
@prisma/clientwas listed in package.json dependencies, the actual generated client code wasn't present in node_modules. Prisma requires a generation step after schema changes to create the necessary TypeScript types and runtime code.📸 Evidence (A photo is required as evidence)
[Attach a screenshot showing the successful Prisma client generation output]
⏰ Time spent breakdown
npx prisma generate: 2 minutes�� Comments
This was a straightforward fix that involved regenerating the Prisma client. The error was preventing the application from starting due to missing generated Prisma client code. After running the generate command, the import error was resolved and the application should now run properly.
The fix ensures that the Prisma client is properly generated and available for import, maintaining the existing database configuration and connection pooling setup.
Thank you for contributing to Volunchain, we are glad that you have chosen us as your project of choice and we hope that you continue to contribute to this great project, so that together we can make our mark at the top!
