I'm using Firebase and have started trying to run a local development instance using the Firebase Emulators. I'm running v8.4.1 of Firebase Tools. When I'm running with the real Firestore database everything works fine. However there is something wrong when I'm using the emulators.
I can set a document and then get it through Javascript but nothing shows in the Firebase Emulators UI and the same in reverse, when I add data through the Firebase Emulators UI it isn't available using get in Javascript. Also, when I use the import and export function of the Firebase Tools CLI none of the data I've added through Javascript is exported and imported. I'm not getting any errors in the browser console.
I'm not sure if there is something wrong I'm doing in initializing Firebase or some other config I'm missing?
I'm running: firebase emulators:start --only functions,firestore

Reset to default 7Turns out the issue was due to the current status of Firebase Tools. I had previously been using Firebase Tools with another project and had to run the use mand for my current project that I was trying to use the emulators with:
firebase use project_name
Now everything works as expected.
