## Introduction While working on the RAHB project, I encountered a Prisma issue in a pnpm monorepo where `prisma generate` could not resolve `@prisma/client`. The project uses: * **pnpm:** 10.15.0 * **Prisma:** 6.19.3 * **@prisma/client:** 6.19.3 * **Next.js:** 15.5.24 * **Backend:** NestJS * **Monorepo:** pnpm workspace The interesting part was that Prisma itself was installed, but the API workspace could not correctly resolve the Prisma Client during generation. This article documents the problem, the diagnosis, the fix, and what happened afterward. # The Problem The initial command was: pnpm --filter @rahb/api exec prisma generate --schema=../../prisma/schema.prisma The command failed with: Environment variables loaded from .env Prisma schema loaded from ..\..\prisma\schema.prisma Error: Could not resolve @prisma/client. Please try to install it with pnpm i @prisma/client and rerun pnpm dlx "prisma generate". ERR_PNPM_RECURSIVE_EXEC_FIRST_FAIL Command "prisma" not found At first glance, this looked like a normal missing dependency problem. However, the project was using a pnpm workspace, so dependency resolution needed to be checked at both the workspace root and the API package level. # Project Structure The relevant structure was approximately: RAHB/ └── rahb/ ├── apps/ │ └── api/ ├── prisma/ │ └── schema.prisma ├── package.json ├── pnpm-workspace.yaml └── node_modules/ The Prisma schema was located outside the API package: ../../prisma/schema.prisma This meant that Prisma generation was being executed from the `@rahb/api` workspace while using the shared root Prisma schema. # Step 1: Check Prisma Versions Before changing anything, I checked the versions installed in the API package: pnpm --filter @rahb/api list prisma @prisma/client The expected result was: @rahb/api dependencies: @prisma/client 6.19.3 devDependencies: prisma 6.19.3 I also checked the entire workspace: pnpm list -r prisma @prisma/client The result confirmed that both the workspace root and API package were using: prisma 6.19.3 @prisma/client 6.19.3 Keeping Prisma CLI and Prisma Client on the same version is important when troubleshooting generated-client and type-resolution issues. # Step 2: Install Prisma Explicitly at the Workspace Root The first attempt to add the packages normally produced a pnpm workspace warning: ERR_PNPM_ADDING_TO_ROOT Running this command will add the dependency to the workspace root, which might not be what you want. Because this was intentionally a workspace-level dependency installation, I explicitly used the `-w` flag: pnpm add -D prisma@6.19.3 @prisma/client@6.19.3 -w Then: pnpm install This ensured that the workspace had a consistent Prisma installation. # Step 3: Generate Prisma Client Again After installing the dependencies, I ran: pnpm --filter @rahb/api exec prisma generate --schema=../../prisma/schema.prisma This time it succeeded: Environment variables loaded from .env Prisma schema loaded from ..\..\prisma\schema.prisma ✔ Generated Prisma Client (v6.19.3) This confirmed that the original Prisma resolution problem had been fixed. The generated client was successfully created under the pnpm-managed `node_modules` structure. # Verifying the Fix The most important verification commands were: pnpm --filter @rahb/api list prisma @prisma/client and: pnpm --filter @rahb/api exec prisma generate --schema=../../prisma/schema.prisma The final dependency state was: @rahb/api dependencies: @prisma/client 6.19.3 devDependencies: prisma 6.19.3 And Prisma generation completed successfully: ✔ Generated Prisma Client (v6.19.3) At this point, Prisma itself was no longer the blocker. # A New Problem Appeared During the Build After Prisma generation succeeded, I ran: pnpm --filter @rahb/api build The build progressed further, but TypeScript compilation failed. The output contained: Found 15 error(s). This distinction is important. The project had moved from: Prisma Client cannot be resolved to: TypeScript compilation errors These are two different problems. # The Remaining Build Errors The remaining errors were spread across several parts of the API. ## 1. Workspace Package Resolution Cannot find module '@rahb/types' File: src/common/order-state-machine.ts This is a workspace/package resolution issue and is independent of Prisma installation. ## 2. Prisma Shutdown Hook Argument of type '"beforeExit"' is not assignable to parameter of type 'never'. File: src/common/prisma/prisma.service.ts The existing Prisma shutdown-hook implementation needs to be reviewed for compatibility with Prisma 6.19.3. ## 3. Prisma Module Import Path Cannot find module '../common/prisma/prisma.module' File: src/modules/admin-operations/admin-operations.module.ts This is an incorrect or unresolved import path rather than a Prisma installation problem. ## 4. Missing DTO Cannot find name 'UpdateProductDto' File: src/modules/catalog/catalog.service.ts The existing DTO structure needs to be checked and the correct DTO imported. ## 5. Prisma JSON Type Another error occurred when passing `optionsJson` to Prisma: Type 'unknown' is not assignable to type 'NullableJsonNullValueInput | InputJsonValue | undefined' File: src/modules/commerce/checkout/checkout.service.ts This is related to TypeScript typing of JSON data being passed into Prisma. # Redis / BullMQ Errors Several remaining errors were unrelated to Prisma. For example: Type '{ ... tls: boolean }' is not assignable to type 'ConnectionOptions' These errors appeared in the reservation and notification workers. Affected areas included: src/modules/commerce/workers/reservation-expiry.worker.ts src/modules/operations/notifications/notifications.service.ts src/modules/operations/notifications/notifications.worker.ts The Redis connection configuration needs to match the installed BullMQ/ioredis types. # Prisma Relation Errors The reservation expiry worker also contained Prisma relation errors. For example: 'order' does not exist in type 'OrderItem$subOrderArgs' and: Property 'orderItem' does not exist These errors indicate that the code was assuming relations that do not match the currently generated Prisma types. The correct approach is to inspect: prisma/schema.prisma and use the relations that actually exist in the schema. This is preferable to changing the schema simply to make TypeScript compile. # Delivery Query Error Another Prisma-related TypeScript error occurred in: src/modules/operations/delivery/delivery.service.ts The code used: findUnique({ where: { orderId } }) But the generated Prisma type reported that `orderId` was not a valid unique selector for `DeliveryOrder`. This means the query needs to follow the actual uniqueness constraints defined by the Prisma schema. For example, depending on the intended business logic, `findFirst` or another appropriate query may be more correct than `findUnique`. # Commission Rule Ordering Error Another error appeared in: src/modules/operations/settlements/commission.service.ts The code attempted: orderBy: [ { priority: 'asc' }, { scope: 'DESTINATION' } ] However, Prisma expects `orderBy.scope` to receive a `SortOrder` such as: 'asc' or: 'desc' rather than a business enum such as: 'DESTINATION' The business priority of commission scopes therefore needs to be implemented separately from Prisma's database sorting syntax. # An Important Lesson One of the most useful lessons from this debugging process is to distinguish between: ### Dependency resolution Could not resolve @prisma/client and: ### Generated-client / TypeScript issues TypeScript compilation errors Fixing the first does not automatically fix the second. In this case, once Prisma Client was successfully generated, the build exposed the actual application-level issues that had previously been hidden behind the Prisma resolution failure. # Final Prisma State After the fix, the project had: Prisma CLI: 6.19.3 @prisma/client: 6.19.3 pnpm: 10.15.0 And: pnpm --filter @rahb/api exec prisma generate --schema=../../prisma/schema.prisma successfully produced: ✔ Generated Prisma Client (v6.19.3) Therefore, the original Prisma installation/resolution issue was successfully resolved. # What Still Needs to Be Fixed The remaining work is application-level TypeScript cleanup: * Resolve `@rahb/types` * Fix the Prisma shutdown hook * Correct the `PrismaModule` import path * Resolve `UpdateProductDto` * Correct Prisma JSON typing * Fix Redis/BullMQ connection typing * Correct Prisma relation queries * Fix `DeliveryOrder` lookup logic * Fix commission-rule ordering * Remove the remaining TypeScript errors The important constraint is that these fixes should be made **without changing the existing architecture or unnecessarily changing the Prisma version**. # Useful Debugging Commands When working with Prisma inside a pnpm monorepo, these commands are useful: ### Check package versions pnpm --filter @rahb/api list prisma @prisma/client ### Check the entire workspace pnpm list -r prisma @prisma/client ### Install matching Prisma versions pnpm add -D prisma@6.19.3 @prisma/client@6.19.3 -w ### Install workspace dependencies pnpm install ### Generate Prisma Client pnpm --filter @rahb/api exec prisma generate --schema=../../prisma/schema.prisma ### Build the API pnpm --filter @rahb/api build # Conclusion The original Prisma problem in the RAHB pnpm monorepo was caused by the workspace not correctly resolving `@prisma/client` when running Prisma generation from the API package. By explicitly installing matching Prisma versions at the workspace level: prisma 6.19.3 @prisma/client 6.19.3 and regenerating the client, Prisma Client generation was restored successfully. The subsequent build errors were not evidence that Prisma was still broken. Instead, they revealed existing TypeScript, package-resolution, Redis/BullMQ, and Prisma relation/type issues that could then be addressed independently. **Final status:** Prisma installation ✅ Prisma version alignment ✅ Prisma Client generation ✅ API TypeScript build ⚠️ Additional code errors remain This separation made the debugging process much clearer and prevented unnecessary changes to the project's architecture or database layer.
