Summary

I am running into an error while testing my android production build on Firebase Test Lab. My app builds without errors on eas through the production profile. However, upon uploading this build file to Firebase Test Lab, the tests fail and indicate that the crash was due to Metro not running. Since this is a production build, the app bundle should not depend on a Metro server. My eas.json file is summarized below.

Note: this same error occurs on the Google Play store, as Google Play uses Firebase Test Lab for pre-screening.

Reproducible demo or steps to reproduce from a blank project

Step 1: eas build -p android Step 2: download the .aab file Step 3: upload the build to Firebase Test Lab / Google Play

For bare projects we are just running gradle build, there is nothing special in the process. If the js bundle is missing it's an issue with your project configuration and not with eas.

Does it work if you build a release APK and install it on the device?
