staticFileマウントしたらなんかPOSTできなかった

import os

from fastapi import FastAPI
from fastapi.staticfiles import StaticFiles
from pydantic import BaseModel


class Chat(BaseModel):
    text: str

app = FastAPI()
this_directory =  os.path.dirname(__file__)
app.mount("/", StaticFiles(directory=os.path.join(this_directory, "static"), html=True), name="static")

@app.post("/chat/")
async def create_item(chat: Chat):
    return chat

app.mount()をルーターより後におけば大丈夫になった

import os

from fastapi import FastAPI
from fastapi.staticfiles import StaticFiles
from pydantic import BaseModel


class Chat(BaseModel):
    text: str

app = FastAPI()

# この部分をmountより前に
@app.post("/chat/")
async def create_item(chat: Chat):
    return chat
	
this_directory =  os.path.dirname(__file__)
app.mount("/", StaticFiles(directory=os.path.join(this_directory, "static"), html=True), name="static")
