SwaggerUI deletion random file in list always removes the last one in the list (e.g. when uploading multiple files to an endpoint)

[nicolastoira]

Example Code

from fastapi import FastAPI
from fastapi import FastAPI, UploadFile, File
from typing import List


app = FastAPI()

@app.post("/Upload_files")
async def upload_external_files(files: List[UploadFile] = File(...), ) -> str:
    print("Files uploaded")

Description

• Open the documentation page /docs where SwaggerUI is shown
• The endpoint /Upload_files looks like this
  
• Let's say we would like to upload several files to the endpoint, therefore we list files 1 to 3 as shown. We then realize that the first file we listed (1) is the wrong one. If we click on the deletion sign on the right of the first file, we expect it to be removed from the list. Instead, it is always the last file in the list to be removed and therefore there is no way to remove a specific file in the list:
  

Is this an issue related to FastAPI, or to SwaggerUI? Is there already a fix?
I updated to the latest FastAPI version, but the issue persists and I'm not sure which version of SwaggerUI is used by FastAPI and if there is already a fix on a latest version of SwaggerUI.

Thanks for the support.
