Help logging first event/error

I have a react native app using expo, and have followed the setup guide here -

I am publishing to a release channel where I want to test things out. If i just run expo publish, it will push a new release to our users, which I dont want to do. In the Sentry dashboard, i see my releases under “Stats” each time i run expo publish --release-channel test, but that is it. I do not see anything logged, and it still says * You’re almost there! Start capturing errors with just a few lines of code.* at the top. Am i missing a step somewhere?

My App.js looks like this:

import App from './app/index';
import Sentry from 'sentry-expo';

Sentry.enableInExpoDevelopment = true;


export default App;

My app.json:

  "expo": {
    "name": "foo",
    "slug": "foo",
    "version": "1.0.10",
    "sdkVersion": "28.0.0",
    "ios": {
      "bundleIdentifier": "foo",
      "buildNumber": "1.0.10",
      "supportsTablet": true,
    "android": {
      "package": "foo",
      "versionCode": 10,
      "icon": "./app/assets/images/app-icon.png",
      "googleServicesFile": "./google-services.json"
    "hooks": {
      "postPublish": [
          "file": "sentry-expo/upload-sourcemaps",
          "config": {
            "organization": "org-name-here",
            "project": "project-name-here",
            "authToken": "authToken-here"
