Bug: Missing isolation scope context breaks request metadata attachment

The refactored code retrieves an isolation scope via commonObjectToIsolationScope at line 29 and sets normalizedRequest metadata on it, but the handleCallbackErrors callback is not wrapped with withIsolationScope. When captureException is called in the error handler, getIsolationScope() at line 42 returns the current global isolation scope - not the one with the request metadata. This causes captured exceptions to be missing request context (like headers) that was set up earlier. The original code used withIsolationScope(isolationScope, ...) to ensure all nested code ran with the correct isolation scope.

Bug: Debug console.log left in test code

A console.log(transactionEvent?.transaction) statement appears to have been left in the test code, likely from debugging. While this is in test code, it will produce unnecessary output during test runs.
