In emulators, realtime database, firestore write (via emulator functions) is showing success but can't see data in the firebase console

[REQUIRED] Environment info

firebase-tools: 7.3.2

Platform: Ubuntu

[REQUIRED] Test case

In emulator, I’m writing to realtime database and firestore, via emulator functions. The write shows success, but I can’t see it’s written to db (firestore, rtdb) in firebase console.

[REQUIRED] Steps to reproduce

Cloud functions:

exports.singleTask = functions.https.onRequest((req, res) => {

	return admin.database().ref(`admin/singleTask/done`)
	.transaction((current_value) => {
		console.log(current_value);
		if (current_value === null || current_value === 0) {
			return (current_value || 0) + 1;
		} else {
			//eslint-disable-next-line consistent-return
			return; // Abort the transaction.
		}

	})
	.then((trans) => {
		if (trans.committed) {
		
			return firestore.doc('col/doc1').set({'key': 'val'});
		
		} else {
			return Promise.reject(new Error('duplicate'));
		}
	})
	.then(_commit => {
		return res.send('updated');
	})
	.catch((err) => {
		if (err.message === 'duplicate') {
			return res.send('duplicate')
		}else{
			console.error(err);
			return res.send('error')
		}
	})
});

[REQUIRED] Expected behavior

In firebase console, RTDB, admin/singleTask/done should be set to 1 && in firestore, col/doc1 should contain key: "val"

[REQUIRED] Actual behavior

Write is successfull in cloudfunctions, but not showing in console.

@hkchakladar for Firestore there’s no easy way to view data in your browser, we’re working on it!

If you want to write back to production, you should not run the DB emulators. So firebase emulators:start --only functions. Then any code that runs in the function will talk to production. Of course then you can’t trigger the functions based on local DB events but that would be a strange combination anyway.

@hkchakladar that’s the intended behavior because it is writing back to the Database Emulator, which can’t be seen by the console.

You can view the data by going to: http://localhost:PORT/admin/singleTask/done.json?ns=YOUR_PROJECT_ID

Make sure to replace PORT with the port the RTDB emulator is using and YOUR_PROJECT_ID with your Firebase project ID.
