# Why

Thanks to @szdziedzic's changes to `www`, if we send a `package.json` along with `eas.json` when setting up a workflow run, EAS will pick the right images based on SDK and RN versions as `eas build` would.

# How

Added uploading `package.json` after uploading `eas.json`, added the new argument to the mutation.

# Test Plan

Tested manually.
