Summary

I get the following error after upgrading Expo and Expo Router to canary and running npm start with experimental typed route support turned on:

  ]
}

The issue occurs on line 10 of expo-router/build/typed-routes/index.js:

const _ctx_shared_1 = require("../../_ctx-shared");

Looking at the relevant directory in node-modules, I don't see _ctx-shared, but I do see it in GitHub, which leads me to believe it's being excluded by the explicit list of included files in Expo Router's package.json. If so, this should be an easy fix: just add that file to the package.json files list.
