Reproduction Example/SDK Setup

Everything works fine locally sending errors and logs to Sentry, but when deployed to cloudflare pages (v3 runtime with node compat flag) the Sentry objected imported seems uninitialized with only the following 4 constants set, but no methods or other properties that are visible from the same console.log messages when I'm working locally.

import * as Sentry from "@sentry/sveltekit";
const { logger } = Sentry;

export const GET = async () => {
  console.log("Sentry =>", Sentry);
  console.log("Sentry logger =>", logger);
  logger.info("Hello from Sentry! (server method)", {
    requestId: "123",
  });
  throw new Error("Sentry Example API Route Error");
};

(log) Sentry => {
  SDK_VERSION: '9.31.0',
  SEMANTIC_ATTRIBUTE_SENTRY_OP: 'sentry.op',
  SEMANTIC_ATTRIBUTE_SENTRY_ORIGIN: 'sentry.origen',
  SEMANTIC_ATTRIBUTE_SENTRY_SAMPLE_RATE: 'sentry.sample_rate',
  SEMANTIC_ATTRIBUTE_SENTRY_SOURCE: 'sentry.source'
}
(log) Sentry logger => null

has anyone else encountered this??

I've got an isolated example that exhibits the same behavior i encountered when implementing this in my real project here: https://github.com/spacethree/cloudflare-sveltekit-sentry

Steps to Reproduce

1. deploy https://github.com/spacethree/cloudflare-sveltekit-sentry to cloudflare pages
2. visit the deployed site's /sentry-example-page
3. click "throw sample error button"

Expected Result

1. Sentry object is debug logged on server with real methods and properties
2. Sentry logger method is debug logged on server
3. "Hello from Sentry! (server method)" should be sent to sentry logging with example structured data attached

Actual Result

1. Sentry object only has the 4 properties (see above)
2. Sentry logger is null
3. access violation attempting to call logger.info
