SDK Setup

Sentry.init({
	dsn: __MY_DSN__,
	tracesSampleRate: 1.0,
});

Steps to Reproduce

1. Create a project using TS 5.0.4
2. Use a tsconfig.json like this

{
  "compilerOptions": {
    "outDir": "lib",
    "allowJs": true,
    "alwaysStrict": true,
    "declaration": true,
    "experimentalDecorators": true,
    "sourceMap": true,
    "inlineSources": true,
    "sourceRoot": "/",
    "lib": ["es2022"],
    "module": "CommonJS",
    "noEmitOnError": false,
    "noFallthroughCasesInSwitch": true,
    "noImplicitAny": true,
    "noImplicitReturns": true,
    "noImplicitThis": true,
    "noUnusedLocals": false,
    "noUnusedParameters": false,
    "resolveJsonModule": true,
    "strict": true,
    "strictNullChecks": true,
    "strictPropertyInitialization": true,
    "stripInternal": true,
    "skipDefaultLibCheck": true,
    "target": "ES2020",
    "incremental": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "moduleResolution": "nodenext"
  },
  "include": ["src/**/*.ts", "test/**/*.ts"],
  "exclude": ["node_modules/", "**/*.d.ts"]
}

3. Create a trace in e.g. src/index.ts

import * as Sentry from "@sentry/node";
Sentry.init({
	dsn: __MY_DSN__,
	tracesSampleRate: 1.0,
});
const transaction = Sentry.startTransaction({ name: "demo" });
transaction.finish()

4. Run tsc
5. Execute node lib/src/index.js

Expected Result

Traces being tracked

Actual Result

Error is thrown on startTransactiion:

TypeError: Cannot read properties of undefined (reading '0')

    at Transaction.startChild (/my-project/node_modules/@sentry/core/cjs/tracing/span.js:156:23)

It appears to be related to this line: https://github.com/getsentry/sentry-javascript/blob/develop/packages/utils/src/misc.ts#L33
My guess is that Uint8Array is not globally defined

This smells an awful lot like #5622

Can you check if you have any dependencies that polyfill the crypto module? Thank you!

Yes, that was the same issue, thanks for the fast response 🙇
