How to fix P6006: Unknown error (Pulse) in Prisma

First, verify which version of Prisma you're using:

npm list prisma @prisma/client

Check your package.json to see the exact version:

{
  "dependencies": {
    "@prisma/client": "7.0.1",  // Example problematic version
    "@prisma/extension-accelerate": "2.0.0"
  },
  "devDependencies": {
    "prisma": "7.0.1"
  }
}

Note the version number - you'll need this to check compatibility.

Accelerate has minimum version requirements:
- Prisma Client: 4.16.1 or higher
- @prisma/extension-accelerate: 1.0.0 or higher (2.0.0+ requires Node.js 18+)

Check the [Prisma Accelerate documentation](https://www.prisma.io/docs/accelerate/getting-started) for the latest compatibility matrix.

If you recently upgraded and encountered P6006, downgrade to the previous stable version:

# Example: Downgrade from 7.0.1 to 7.0.0
npm install [email protected] @prisma/[email protected]

Or specify a known stable version:

npm install [email protected] @prisma/[email protected]

Then regenerate your Prisma Client:

npx prisma generate

Restart your application and test the connection.

While waiting for Accelerate support, bypass Accelerate temporarily by switching to a direct connection:

# .env - Comment out Accelerate URL
# DATABASE_URL="prisma://accelerate.prisma-data.net/?api_key=..."

# Use direct PostgreSQL connection instead
DATABASE_URL="postgresql://user:password@host:5432/database"

Update your Prisma Client initialization to remove the Accelerate extension:

// Before (with Accelerate)
import { PrismaClient } from '@prisma/client'
import { withAccelerate } from '@prisma/extension-accelerate'

const prisma = new PrismaClient().$extends(withAccelerate())

// After (direct connection)
import { PrismaClient } from '@prisma/client'

const prisma = new PrismaClient()

This lets you continue development while waiting for Accelerate compatibility.

Check if your Prisma version is officially supported:

1. Visit the [Prisma GitHub releases](https://github.com/prisma/prisma/releases)
2. Check the [Accelerate troubleshooting guide](https://www.prisma.io/docs/accelerate/troubleshoot)
3. Search for known issues: https://github.com/prisma/prisma/issues?q=P6006

If the version was recently released, Accelerate support may take a few days to roll out. Consider pinning to the last stable version in your package.json:

{
  "dependencies": {
    "@prisma/client": "6.0.0"  // Pin instead of "^6.0.0"
  }
}
