Problem

Bug description When trying to use `findMany()` (or any other method) on a model, prisma client crashes and the following line appears in my log: `Segmentation fault (core dumped)`. This only happens if I use PostgreSQL as far as I know, this first appeared when I switched to PostgreSQL from mysql. How to reproduce 1. Initiate a new prisma project (make sure to use PostgreSQL) and generate the client - no errors there 2. Write a simple client which fetches some data from the databse 3. The script crashes and `Segmentation fault (core dumped)` gets logged in the console Expected behavior The script does not crash. Prisma information Example schema: [code block] Example test client: [code block] Environment & setup - OS: Pop!_OS (`Linux pop-os 5.15.5-76051505-generic #202111250933~1638201579~21.04~09f1aa7-Ubuntu SMP Tue Nov 30 02: x86_64 x86_64 x86_64 GNU/Linux`) - Database: PostgreSQL v14.1 (Ubuntu 14.1-1.pgdg21.04+1) - Node.js version: v17.2.0 Prisma Version [code block]

Fix Segmentation Fault in Prisma Client with PostgreSQL

Medium Risk

The segmentation fault occurs due to a compatibility issue between the Prisma Client and the specific version of PostgreSQL being used, potentially exacerbated by the Node.js version. This can be caused by native dependencies or incorrect handling of data types between Prisma and PostgreSQL.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Update Prisma Client

    Ensure you are using the latest version of Prisma Client, as many bugs and compatibility issues are resolved in newer releases.

    bash
    npm install @prisma/client@latest
  2. 2

    Check Node.js Version

    Downgrade Node.js to a more stable version, such as LTS (e.g., v16.x), as the current version may have compatibility issues with native modules used by Prisma.

    bash
    nvm install 16 && nvm use 16
  3. 3

    Verify PostgreSQL Connection String

    Double-check your PostgreSQL connection string in the .env file to ensure it is correctly formatted and all required parameters are included.

    yaml
    DATABASE_URL="postgresql://USER:PASSWORD@HOST:PORT/DATABASE"
  4. 4

    Re-generate Prisma Client

    After making changes, re-generate the Prisma Client to ensure it is properly configured with the latest schema and settings.

    bash
    npx prisma generate
  5. 5

    Test with Simple Query

    Run a simple query using the Prisma Client to verify that the segmentation fault no longer occurs. Use a basic findMany() call on a known model.

    typescript
    const users = await prisma.user.findMany();

Validation

Confirm that the script runs without crashing and that the expected data is returned from the database. Monitor logs for any segmentation fault messages.
