Internal server error while trying to get uploaded file name in FastAPI

What I am trying is to upload an image using html template and to create a copy of the image by generating random names and to display the new name in a webpage.

from fastapi import FastAPI,File, UploadFile, Request
from fastapi.responses import HTMLResponse
from fastapi.staticfiles import StaticFiles
from fastapi.templating import Jinja2Templates
import shutil
import os
import datetime
import string
import random


A = datetime.datetime.now()
N = 10
ran = ''.join(random.choices(string.ascii_uppercase + string.digits, k= N))

           


app = FastAPI()

app.mount("/static", StaticFiles(directory="static"), name="static")


templates = Jinja2Templates(directory="templates")


@app.get("/uploadfile", response_class=HTMLResponse)
async def read_item(request: Request ):
    return templates.TemplateResponse("imageupload.html", {"request": request})

@app.post("/uploadfile")
async def create_image(request:Request,image: UploadFile = File(...)):
    abc = os.path.splitext(image.filename)[-1]
    print(abc)
    newname =image + str(A) + ran + abc
    print(newname)
    image.filename = newname
    imagepath = "/static/media/" + image.filename
    print(imagepath)

    with open(os.path.join("./static/media/",image.filename),"wb+") as buffer:
        shutil.copyfileobj(image.filename, buffer)
    return templates.TemplateResponse("imagename.html",{"request": request,"image_path":imagepath})

Please edit your code with proper formatting, so others can easily test and debug your code.
