Langserver could not import module app.server

Question

I am trying to use the tool lanchain and langserver, and create a api from a template. Steps I took:

1. create server template

langchain app new my-app --package rag-conversation

2. copy in the code provided in the cmd after the installation is ready

@app.get("/")
async def redirect_root_to_docs():
    return RedirectResponse("/docs")

add_routes(app, rag_conversation_chain, path="/rag-conversation")

3. cd into my-app folder and run langchain serve in the cmd.

After which the server cant seem to start and throws this error

INFO:     Will watch for changes in these directories: 
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Started reloader process [10212] using WatchFiles
ERROR:    Error loading ASGI app. Could not import module "app.server".

Does anyone know how to aproach this issue. There is no -v command option so this is all the information I have to go by.

The project structure is the following:

this shows that app does contain the server file.

and the server file has the follwing information inside:

from fastapi import FastAPI
from fastapi.responses import RedirectResponse
from langserve import add_routes
from rag_conversation import chain as rag_conversation_chain

app = FastAPI()


@app.get("/")
async def redirect_root_to_docs():
    return RedirectResponse("/docs")

add_routes(app, rag_conversation_chain, path="/rag-conversation")

if __name__ == "__main__":
    import uvicorn

    uvicorn.run(app, host="0.0.0.0", port=8000)

If you know a solution for this issue please be descriptive, I have found some people encountering something similar a few months ago,https://github.com/langchain-ai/opengpts/issues/61, but there they were talking about some dependency issue and requirements.txt of which I can't even find in my app structure.
