@sentry/node v9.40+ breaks OpenAI imports when tracesSampler is configured

[mfazekas]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/node

SDK Version

9.43.0

Framework Version

Node 22.16.0

Link to Sentry event

N/A - This is a build/import error

Reproduction Example/SDK Setup

https://github.com/mfazekas/sentry-openai-repro

Steps to Reproduce

1. Clone the reproduction repository: https://github.com/mfazekas/sentry-openai-repro
2. Run npm install
3. Run npm test

The minimal reproduction consists of two files:

sentry.ts:

import * as Sentry from '@sentry/node'

Sentry.init({
  dsn: 'https://example@sentry.io/123456',
  environment: 'test',
  sampleRate: 1.0,
  tracesSampler: () => {
    return 1.0
  },
})

export default Sentry

index.ts:

// Import Sentry first
import './sentry'

// Then import OpenAI
import OpenAI from 'openai'

// This will fail with: TypeError: import_openai.default is not a constructor
const client = new OpenAI({ apiKey: 'dummy-key' })
console.log('✓ OpenAI client created successfully!')

Expected Result

The OpenAI client should be created successfully without errors.

Actual Result

TypeError: import_openai.default is not a constructor

Additional Context

Version-specific findings:

• ✅ Works: @sentry/node v8.38.0
• ✅ Works: @sentry/node v9.0.0
• ✅ Works: @sentry/node v9.20.0
• ✅ Works: @sentry/node v9.39.0
• ❌ Fails: @sentry/node v9.40.0
• ❌ Fails: @sentry/node v9.43.0

The issue was introduced in v9.40.0.

Key findings:

1. The issue ONLY occurs when tracesSampler is configured
2. The issue ONLY occurs when Sentry is initialized in a separate file that is imported
3. Setting registerEsmLoaderHooks: false does NOT fix the issue
4. The issue does NOT occur when both Sentry and OpenAI are imported in the same file

Workarounds:

1. Remove tracesSampler configuration
2. Use tracesSampleRate instead of tracesSampler
3. Import OpenAI before initializing Sentry
4. Downgrade to @sentry/node v9.39.0 or earlier
5. Initialize Sentry and import OpenAI in the same file

This appears to be related to how Sentry instruments modules when tracesSampler is enabled. The issue is similar to #12414 but manifests differently (v8 shows "API.Completions is not a constructor" while v9.40+ shows "import_openai.default is not a constructor").

Environment

• Node.js: v22.16.0
• @sentry/node: 9.43.0
• openai: ^4.93.0
• typescript: ~5.8.3
• tsx: 4.19.3

@RulaKhaled Has this Issue been fixed?
Running into the same exact issue

[RulaKhaled]

Hello @egelhaus, you should not see this error with v9.44.0.
v10.2.0 also includes a stable release for OpenAI. Let me know if this issue still persists for you
