[REQUIRED] Version info

firebase-tools:

[REQUIRED] Test case

import { onCall } from 'firebase-functions/https';
import { traceContext } from 'firebase-functions/lib/common/trace';

export const callable = onCall((request) => {
  logger.info('Hello from Firebase!');
  // it would be nice to be able to access trace context to use it for adding meta information to firebase documents or forward it if doing specific calls.
  logger.info("traceContext", traceContext);
});

[REQUIRED] Steps to reproduce

firebase deploy

[REQUIRED] Expected behavior

deployment works, and I get trace information.

[REQUIRED] Actual behavior

deployment fails with error

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/common/trace.js' is not defined by "exports" in *************/node_modules/firebase-functions/package.json

}

Were you able to successfully deploy your functions?

no

Alternative

wrap every call in own AsyncLocalStorage and/or use otel and extract traceparent or X-GOOGLE-TRACE header again/by ourself

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
