eas update is using cache env vars

Summary

I have an expo project that is bare and uses EAS update. We have an env var called EXPO_PUBLIC_UPDATE_VERSION that we use to track the versioning of updates in any bug reports.

When I push an update, it does not always receive this value correctly. After some debugging I found that if I run npx expo start -c and then eas update the EXPO_PUBLIC_UPDATE_VERSION is updated correctly when the app receives the update.

This shouldn't be the case, the update SHOULD push the current values in .env, not any cached values in the bundler.

Managed or bare?

Bare

Reproducible demo or steps to reproduce from a blank project

Create an environment variable with EXPO_PUBLIC prefix that is an int.

Make a build

Send and receive the update on device

Do this a few times and verify the value after receiving the update

This can be fix by running npx expo start -c before eas update

@byCedric / @EvanBacon - could npx expo export not be clearing metro cache?

[hesscbjr]

Do I need to run npx expo export separately? Or is that called when I run npx expo update?
