P6005: Invalid parameters (Pulse)

What this error means

The P6005 error in Prisma indicates that invalid parameters were supplied to a Prisma Pulse operation. Prisma Pulse is the real-time data synchronization service that enables live queries and subscriptions to database changes. This error is part of the P6000-P6999 range of Prisma errors that relate to Prisma Pulse functionality. The P6005 error specifically occurs when: 1. **Transaction parameters are out of bounds**: Parameters like transaction timeout values exceed the maximum allowed limits for the Pulse service 2. **Incompatible Prisma version**: The chosen Prisma version is not compatible with Prisma Pulse. This can occur when using an unstable development version that has been pruned or removed 3. **Invalid configuration options**: Subscription or connection configuration contains unsupported or malformed parameter values 4. **Type mismatches**: Parameters are passed with incorrect data types (e.g., string instead of number for timeout) When Prisma Pulse receives a request with invalid parameters, it immediately rejects the operation with the P6005 error to prevent misconfigured subscriptions and ensure service stability.

Typical symptoms

  • Prisma Pulse subscriptions fail with "P6005: Invalid parameters (Pulse)" error
  • Application startup fails when initializing Pulse connections
  • Real-time subscription requests are immediately rejected
  • Error appears when setting transaction timeout values in Pulse queries
  • Incompatible Prisma version warning followed by P6005 errors
  • Configuration validation errors during Pulse initialization

Common causes

  1. Transaction timeout value exceeds the maximum allowed limit (typically over 60 seconds for Pulse)
  2. Using an incompatible or unstable Prisma version that is not supported by Pulse
  3. Passing incorrect data types for Pulse parameters (string instead of number, etc.)
  4. Invalid or malformed subscription configuration options
  5. Using deprecated Pulse API parameters or syntax
  6. Version mismatch between @prisma/client and @prisma/engines packages
  7. Passing undefined or null values for required Pulse parameters

How to fix "P6005: Invalid parameters (Pulse)"

1Check your Prisma version compatibility

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

bash
# 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:

bash
npm install @prisma/client@latest @prisma/engines@latest prisma@latest
npx prisma generate
2Validate transaction timeout parameters

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

typescript
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.

3Review Pulse subscription configuration

Check that your Pulse subscription parameters are correctly formatted:

typescript
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

4Update all Prisma dependencies consistently

Ensure version consistency across all Prisma packages:

bash
# Check all Prisma packages
npm list | grep prisma

# Should output:
# @prisma/client@5.x.x
# @prisma/engines@5.x.x
# prisma@5.x.x

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

bash
# 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:

bash
npx prisma generate

Restart your application to apply the changes:

bash
npm run dev  # or your start command
5Test with simplified Pulse configuration

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

typescript
// 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:

bash
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.

6Check Prisma Dashboard for Pulse configuration

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.

7Contact Prisma support with error details

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

1. Collect error details:

bash
# 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

Advanced notes

Pulse Version Requirements: P6005 errors can indicate version incompatibility. Prisma Pulse is continuously evolving, and older or development versions may not support current parameter formats. Always use the latest stable version from npm.

Parameter Validation: The P6005 error is Prisma's way of validating parameters before sending requests to the Pulse service. This is a protective measure - fixing the validation errors prevents misconfigured subscriptions that would fail at runtime.

Development vs Canary Versions: If you installed Prisma from a development branch or canary release, those versions are frequently pruned and removed. The Pulse service may not recognize them, resulting in P6005 errors. Always use stable npm releases.

Custom Pulse Configuration: If you're using custom Pulse server configuration or self-hosted Pulse, verify that your custom parameters match the API specification for your Pulse version.

Debugging with Logs: Enable verbose Prisma logging to see what parameters are being sent:

typescript
const prisma = new PrismaClient({
  log: [
    { emit: 'event', level: 'query' },
    { emit: 'stdout', level: 'info' },
    { emit: 'stdout', level: 'warn' },
    { emit: 'stdout', level: 'error' },
  ],
})

prisma.$on('query', (e) => {
  console.log('Query:', e.query)
  console.log('Params:', e.params)
})

This helps identify whether parameters are being passed correctly.

Database Feature Compatibility: Pulse requires specific PostgreSQL features:
- Logical replication slots
- Publication mechanism
- Native PostgreSQL streaming

If your database environment doesn't support these (e.g., some managed services restrict these features), Pulse won't work properly and may return validation errors.

Migration from Accelerate to Pulse: If migrating from Prisma Accelerate to Pulse, parameter handling differs. Accelerate and Pulse have different timeout limits and configuration options. Review the official migration guide when switching.
