`TypeError: options.transport is not a function` with Sentry.init and transport=undefined

[cs4inctec]

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

9.2.0

Framework Version

Link to Sentry event

Reproduction Example/SDK Setup

Sentry.init({
        dsn: config.dsn || undefined,
        release: config.release || version || undefined,
        environment: config.environment || undefined,
        integrations: [
          Sentry.extraErrorDataIntegration({
            depth: 10,
            captureErrorCause: true,
          }),
        ],
         transport: config.transport as TransportType,
      });

type TransportType = Sentry.NodeOptions['transport'];

after upgrading from SDK 7 to 9, this error occurs. The Sentry init Api itself is seemingly the same / types didn't change, but when providing an undefined for transport the error is now thrown.

Steps to Reproduce

set transport to undefined

Expected Result

no error

Actual Result

TypeError: options.transport is not a function
