How to fix P6005: Invalid parameters (Pulse) in Prisma

Verify that you are using a stable, supported version of Prisma that is compatible with Prisma Pulse:

# Check current Prisma version
npm list prisma @prisma/client

# Expected: Both should be stable versions (e.g., 5.x.x)
# NOT: alpha, beta, dev, canary, or rc versions

Prisma Pulse requires:
- @prisma/client 5.0.0 or higher
- Compatible @prisma/engines version
- Stable release versions only

If you're using a development or unstable version, update to the latest stable release:

npm install @prisma/client@latest @prisma/engines@latest prisma@latest
npx prisma generate

If using transactions with Pulse, ensure timeout values are within acceptable limits:

import { PrismaClient } from '@prisma/client'

const prisma = new PrismaClient()

// WRONG: Timeout too high (exceeds limit)
await prisma.$transaction(
  async (tx) => {
    // Your queries here
  },
  { timeout: 300000 } // 300 seconds - TOO HIGH for Pulse
)

// CORRECT: Reasonable timeout value
await prisma.$transaction(
  async (tx) => {
    // Your queries here
  },
  { timeout: 30000 } // 30 seconds - Within acceptable range
)

For Prisma Pulse, keep timeout values:
- Minimum: 1000ms (1 second)
- Maximum: 60000ms (60 seconds) for most operations
- Recommended: 10000-30000ms for typical queries

If your operations legitimately need longer, consider using direct database connections instead of Pulse for those specific operations.

Check that your Pulse subscription parameters are correctly formatted:

import { PrismaClient } from '@prisma/client'

const prisma = new PrismaClient()

// CORRECT: Valid subscription configuration
const subscription = prisma.user.subscribe({
  create: {
    include: ['name', 'email'] // Include only needed fields
  }
})

// WRONG: Invalid or unsupported parameters
const subscription = prisma.user.subscribe({
  create: {
    timeout: '30s' // WRONG: Should be a number in milliseconds, not string
  }
})

// CORRECT: Using proper parameter format
const subscription = prisma.user.subscribe({
  create: {
    // Valid options depend on Prisma version
  }
})

For valid subscription parameters, check:
1. All parameters use correct data types (numbers not strings for timeout/duration)
2. Parameter names match the Pulse API exactly
3. No deprecated or renamed parameters from previous versions
4. All required parameters are provided

Ensure version consistency across all Prisma packages:

# Check all Prisma packages
npm list | grep prisma

# Should output:
# @prisma/[email protected]
# @prisma/[email protected]
# [email protected]

If versions are mismatched, update them to the same version:

# Clean install approach
npm uninstall prisma @prisma/client @prisma/engines
npm install --save-dev prisma@latest
npm install @prisma/client@latest

# Or update approach
npm update prisma @prisma/client

After updating, regenerate the Prisma Client:

npx prisma generate

Restart your application to apply the changes:

npm run dev  # or your start command

Create a minimal test script to verify Pulse is working with valid parameters:

// test-pulse.ts
import { PrismaClient } from '@prisma/client'

const prisma = new PrismaClient({
  log: ['info', 'warn', 'error'],
})

async function testPulse() {
  try {
    console.log('Testing Pulse with minimal configuration...')

    // Simple subscription with no extra parameters
    const subscription = prisma.user.subscribe({
      create: {}
    })

    console.log('Subscription created successfully')

    // Close immediately
    subscription.return()

    console.log('Test PASSED: Pulse is working correctly')
    process.exit(0)
  } catch (error) {
    console.error('Test FAILED:', error.message)
    console.error('Code:', error.code)
    process.exit(1)
  } finally {
    await prisma.$disconnect()
  }
}

testPulse()

Run the test:

npx tsx test-pulse.ts

If this minimal test passes, your Pulse setup is valid. If it still fails, the issue may be with your API key or database connection instead of parameters.

Verify your Pulse setup in the Prisma Dashboard:

1. Visit Prisma Dashboard:
- Go to https://cloud.prisma.io
- Select your project
- Navigate to the Pulse section

2. Verify Pulse is enabled:
- Check that Pulse is marked as "Active"
- Confirm your database type (PostgreSQL) is supported
- Check that logical replication is enabled

3. Review API Keys:
- Ensure your API key is valid and active
- Confirm the key has Pulse permissions enabled
- Check that the key has not exceeded usage limits

4. Database Requirements:
- PostgreSQL version 12+ is required
- Logical replication (wal_level = logical) must be enabled
- The database role must have superuser access (on Starter plan)

5. Check for service status:
- Look for any Pulse service notifications or maintenance windows
- Verify Pulse API endpoints are responsive

If you find any configuration issues, update your settings and regenerate your API key if needed.

If P6005 persists after trying these steps, gather diagnostic information:

1. Collect error details:

# Capture full error output
node -e "require('your-app')" 2>&1 | tee error-log.txt

2. Document your setup:
- Prisma version: npm list prisma @prisma/client
- Node.js version: node --version
- Database: PostgreSQL version and Pulse status
- Environment: Local development, staging, or production

3. Provide your transaction/subscription code:
- Share the exact parameters being passed
- Include any custom Pulse configuration

4. Contact Prisma support:
- Prisma Dashboard support portal
- GitHub Discussions: https://github.com/prisma/prisma/discussions
- Prisma Discord server for community help
- Include the error log and setup details in your report

Include these details in your support request:
- Full error message and stack trace
- Steps to reproduce the issue
- Prisma version information
- Your transaction/subscription parameters
- Any recent version upgrades before the error started
