Asgi server

When using the asgi app functionality, I'm getting a 404 for everything except the root. Any ideas?

server = (
    marimo.create_asgi_app()
    .with_app(path="", root="./index.py")
    .with_app(path="/easy-entry", root="./production/easy-entry.py")
    .with_app(
        path="/print-leader-coverage",
        root="./production/print-leader-coverage.py",
    )
    .with_app(
        path="/print-section",
        root="./production/print-section.py",
    )
)

# Create a FastAPI app
app = FastAPI()

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

server = (
    marimo.create_asgi_app()
    .with_app(path="", root="./index.py")
    .with_app(path="/easy-entry", root="./production/easy-entry.py")
    .with_app(
        path="/print-leader-coverage",
        root="./production/print-leader-coverage.py",
    )
    .with_app(
        path="/print-section",
        root="./production/print-section.py",
    )
)

# Create a FastAPI app
app = FastAPI()

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

/ works and is a full notebook, /print-section gives me a marimo 404

What happens when you visit /easy-entry/ (with a slash at the end)

Same thing If I mount it here:

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

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

I also can't visit /marimo (404)

Ok I figured it out. This fixed it (I figured it out from looking at the smoke test file: https://github.com/marimo-team/marimo/blob/7a1459dfa5088656b76feeea40fb7109e3f3b221/marimo/_smoke_tests/custom_server/my_server.py

The fix is to put the index notebook last: marimo.create_asgi_app() .with_app(path="/easy-entry", root="./production/easy-entry.py") .with_app( path="/print-leader-coverage", root="./production/print-leader-coverage.py", ) .with_app( path="/print-section", root="./production/print-section.py", ) .with_app(path="", root="./index.py") It was matching everything, and so it was index.py's notebook serving that 404 I'm not 100% sure I'd call that a bug, but it'd be worth documenting it here since this example doesn't work: https://docs.marimo.io/guides/deploying/programmatically.html Thanks again for shipping this though! My users are gonna love it 🙂

oh nice! now that you say that, it makes a lot of sense. i think we should handle this and document it for sure, thanks for debugging this
