Uvicorn on top of poetry suppresses output of print calls

[LzrdDragon]

I have a problem that uvicorn doesn't call or show results of my prints from api endpoint and flush=True doesn't work, I guess it may be related to a poetry because I running my uvicorn through it.
The command I use to start a server is

poetry run start

app:

from fastapi import FastAPI
from iteration_1.server import router as iteration_1_router
import uvicorn


def init_routers(app: FastAPI) -> FastAPI:
    app.include_router(iteration_1_router, tags=["iteration_1"])
    return app


def get_app() -> FastAPI:
    app: FastAPI = FastAPI()
    init_routers(app)
    return app


app = get_app()


def start():
    """Launched with `poetry run start` at root level"""
    uvicorn.run("asgi:app", host="0.0.0.0", port=8000, reload=True, workers=1, log_level='debug', access_log=True)

api:

@router.post(
    URLs.post_link.value,
    name="post_Link",
    summary="Post Link",
    response_model=LinksListResponse
)
async def post_link(links_list: LinksList):
    response = LinksListResponse(links=[])
    print(f'response={response}', flush=True)
    print(links_list, flush=True)
    for link in links_list.links:
        print(link, flush=True)
        title = await get_title(link.link)
        link_response = LinkResponse(url=link.link, title=title)
        response.links.append(link_response)
    return response

request: (I'm running this script)

links = [
    Link(link="https://huawei-krsk.ru"),
    Link(link="https://google.com")
]

links_list = LinksList(links=links).json()
print(links_list)


async def post_links_to_api(data_list):
    async with aiohttp.ClientSession() as session:
        async with session.post(
            "http://127.0.0.1:8000/iteration_1/post-links",
            json=jsonable_encoder(data_list)
        ) as response:
            print(response.status)
            print(await response.text())


if __name__ == '__main__':
    asyncio.run(post_links_to_api(links_list))

uvicorn doesn't print anything from the api

Here are prints from the request script(which I run), work fine

It was a problem with pydantic validation, so, so sorry about that, printing and logging works
