Angular @cypress/schematic produces "Missing baseUrl in compilerOptions. tsconfig-paths will be skipped"

[MikeMcC399]

Current behavior

After scaffolding Angular 19 with @cypress/schematic, then running Cypress with npx cypress run the following warning is output:

Missing baseUrl in compilerOptions. tsconfig-paths will be skipped

Desired behavior

@cypress/schematic should set up a project so that no warning is produced when running Cypress.

Test code to reproduce

Set up project with:

npm install -g @angular/cli@19
ng new angular-app # select CSS, no server-side rendering
cd angular-app
ng add @cypress/schematic --e2e --component

this is available in https://github.com/MikeMcC399/cypress-test-tiny/tree/31433-angular-19/angular-app:

git clone --branch 31433-angular-19 https://github.com/MikeMcC399/cypress-test-tiny
cd cypress-test-tiny
cd angular-app
npm ci
npm start

then, in a separate terminal window execute:

export DEBUG=cypress:server:ts-node
npx cypress run

[MikeMcC399]

The issue can be resolved by adding

  "compilerOptions": {
    "baseUrl": "./",

to tsconfig.json

It needs to be clarified whether it would be the responsibility of @cypress/schematic to modify this file, which has been created by the command ng new angular-app.
