Context

This error suggests that there might be an attempt to handle a lifespan event, which Django's ASGI application does not support. This could be due to a misconfiguration in the ASGI server or an incorrect setup in the application that tries to handle unsupported events.

Suggested Actions

1. ASGI Server Configuration: Ensure your ASGI server is configured to handle only HTTP and WebSocket connections.
2. Middleware and Third-Party Packages: Review any middleware or third-party packages that might be handling ASGI events.
3. Dependencies: Ensure all dependencies are up to date.

Additional Information

For further assistance, consider consulting the documentation for your ASGI server or any third-party packages you are using.

The ValueError you're encountering is due to Django's ASGI application trying to handle a lifespan event, which it doesn't support. Here's how you can address this issue:

1. ASGI Server Configuration: Ensure your ASGI server (like Daphne, Uvicorn, or Hypercorn) is configured to handle only HTTP and WebSocket connections. Lifespan events should be disabled or ignored.

2. Review Middleware and Third-Party Packages: Check if any middleware or third-party packages are attempting to handle ASGI lifespan events. These should be configured to only process HTTP and WebSocket events.

3. Dependencies: Make sure all your dependencies are up to date, as newer versions might have fixes for such issues.

The asgi.py file in your project is correctly set up to expose the ASGI application. The issue likely lies in the server configuration or external packages. Please review these areas to resolve the error.
