error when running a react-router v7 app with @splinetool/runtime installed

[miguelvictor]

What version of Bun is running?

1.2.2+c1708ea6a

What platform is your computer?

Darwin 24.2.0 arm64 arm

What steps can reproduce the bug?

1. create a new react router v7 app like in https://reactrouter.com/start/framework/installation
2. install the @splinetool/runtime package
3. use it somewhere like so <Spline scene="/assets/spline/scene.splinecode" />
4. initiate build with bun bun --bun run build
5. start the app with bun bun --bun run start

What is the expected behavior?

the react-router app should run normally

What do you see instead?

interesting, same error here #16941 (comment), except I don't think bun is building for your case.
