**Describe the bug** Using a ComponentState component causes a frontend exception when running a Reflex application in production mode (reflex run --env prod). It only happens for reflex 0.9.x and run with: reflex run --env prod. The application works as expected without any exceptions during development (reflex run --env dev), but when running in production mode (reflex run --env prod), the frontend throws the following error: [Reflex Frontend Exception] TypeError: d is not a function TypeError: d is not a function at Socket.<anonymous> (http://localhost:3001/assets/createLucideIcon-Bd4MDh-a.js:15:10561) at Emitter.emit (http://localhost:3001/assets/createLucideIcon-Bd4MDh-a.js:1:6018) at Socket.emitEvent (http://localhost:3001/assets/createLucideIcon-Bd4MDh-a.js:1:37733) at Socket.onevent (http://localhost:3001/assets/createLucideIcon-Bd4MDh-a.js:1:37540) at Socket.onpacket (http://localhost:3001/assets/createLucideIcon-Bd4MDh-a.js:1:37184) at Emitter.emit (http://localhost:3001/assets/createLucideIcon-Bd4MDh-a.js:1:6018) at http://localhost:3001/assets/createLucideIcon-Bd4MDh-a.js:1:43264 **To Reproduce** Steps to reproduce the behavior: 1. Create a new Reflex application with the code pasted above 2. Run the application in production mode: reflex run --env prod 3. Observe the frontend exception in terminal - Code/Link to Repo: ```python import reflex as rx from rxconfig import config class TestComponentState(rx.ComponentState): name: str @classmethod def get_component( cls, name: str, ): return rx.flex(rx.text(name)) def index() -> rx.Component: return rx.container( rx.color_mode.button(position="top-right"), rx.vstack( rx.heading("Welcome to Reflex!", size="9"), rx.text( "Get started by editing ", rx.code(f"{config.app_name}/{config.app_name}.py"), size="5", ), TestComponentState.create(name="Test Component State"), spacing="5", justify="center", min_height="85vh", ), ) app = rx.App() app.add_page(index) ``` **Expected behavior** production mode without any frontend exceptions. **Screenshots** If applicable, add screenshots to help explain your problem. **Specifics (please complete the following information):** - Python Version: 3.11 - Reflex Version: 0.9.4 - OS: Linux - Browser (Optional): Chrome **Additional context** Add any other context about the problem here.
