Package subpath './schema.json' is not defined by "exports" with CLI v19.1.0-next.1

[cexbrayat]

Command

e2e

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

19.1.0-next.0

Description

Running ng e2e in a new CLI project, with Cypress added via the official schematics throws:

An unhandled exception occurred: Package subpath './schema.json' is not defined by "exports" in /node_modules/cypress/package.json

This may be an issue with cypress itself of course, but this was previously working with v19.1.0-next.0.
This looks related to 2b8a02b

Minimal Reproduction

Run:

npx @angular/cli@next new schema-e2e --defaults --no-routing
cd schema-e2e
npm config set legacy-peer-deps=true --location=project
ng add @cypress/schematic@2.5.2 --e2e --no-component --skip-confirmation
ng e2e

Exception or Error

An unhandled exception occurred: Package subpath './schema.json' is not defined by "exports" in /node_modules/cypress/package.json
