How to implement Firebase transactions with read operations after write operations

Question

Is there a way to implement read operations after write operations in nodejs for cloud and background functions?

As stated in docs , only server client libraries support transactions with read operations after write operations. But I can't implement one to not trigger error:

Error: Firestore transactions require all reads to be executed before all writes.
    at Transaction.get (/workspace/node_modules/@google-cloud/firestore/build/src/transaction.js:76:19)
    at /workspace/lib/firestore/tests-write.js:46:11
    at processTicksAndRejections (internal/process/task_queues.js:97:5)
    at async Transaction.runTransaction (/workspace/node_modules/@google-cloud/firestore/build/src/transaction.js:323:26)
    at async /workspace/lib/firestore/tests-write.js:43:5 

I'm using "firebase-admin": "^9.6.0" that uses @google-cloud/firestore "4.5.0" and "firebase-functions": "^3.13.2"

Background function (trigger):

const onFirestoreTestsWrite = functions.firestore
  .document('tests/{testId}')
  .onWrite(async (change, context) => {
    await admin.firestore().runTransaction(async (t) => {
      const testDoc = await admin.firestore().collection('tests').doc().get();
      t.set(testDoc.ref, {});
      t.get(testDoc.ref);
    });
  });

Cloud function (http):

const tests_get = async (req, res) => {
  try {
    const test = await admin.firestore().runTransaction(async (t) => {
      const testDoc = await admin.firestore().collection('tests').doc().get();
      t.set(testDoc.ref, {});
      return t.get(testDoc.ref);
    });
    res.send({id: test.id});
  } catch (e) {
    res.status(400).send({ error: e['message'] });
  }
};

Docs stated wrong and server libraries doesn't support reads after writes. Documentation will be fixed soon.

From the point of code, there's no way to overcome such situation.
