@copilot There is a lot of error while building with rollup:

@copilot There is a lot of error while building with rollup:

...

Fixed in d7e2e0e. The issue was caused by my initial npm install upgrading the package-lock.json lockfileVersion from 2 to 3, which also upgraded many dependencies and caused TypeScript to be stricter about Flow type annotations in .js files.

I've now corrected the package-lock.json to only add the @typescript/native-preview package without upgrading other dependencies. The rollup build now completes successfully without errors.
