Deploying as a FastAPI application

[pkdash]

I was following this documentation (https://docs.marimo.io/guides/deploying/programmatically.html) to deploy marimo notebooks. However, I am getting some errors. Hope someone can help me resolve this issue!

The code in my main.py looks like this:

import marimo
from fastapi import FastAPI

# Create a marimo asgi app
server = (
    marimo.create_asgi_app()
    .with_app(path="", root="./app/pages/index.py")
    .with_app(path="/hsclient", root="./app/pages/demo_hsclient.py")
)
app = FastAPI()

app.mount("/", server.build())

# Run the server
if __name__ == "__main__":
    import uvicorn

    uvicorn.run(app, host="localhost", port=8000)
