[lfgogogo]

I have started the server,created a account,and imported my data by a .txt file,but when i start to label my data,i get an error below.I just don't know why i have imported my data but get an error like this while labeling.And my .txt file is below,i start LS by 'label-studio',data server by 'python -m http.server 8081 -d'.

cors problem:

.txt file:

data server console error:

It says an existing connection was forcibly closed by the remote host.

Starting python simple http module will not allow CORS. Use following script to start a simple http server with CORS enabled
https://stackoverflow.com/questions/21956683/enable-access-control-on-simple-http-server
```#!/usr/bin/env python3
from http.server import HTTPServer, SimpleHTTPRequestHandler, test
import sys

class CORSRequestHandler (SimpleHTTPRequestHandler):
def end_headers (self):
self.send_header('Access-Control-Allow-Origin', '*')
SimpleHTTPRequestHandler.end_headers(self)

if __name__ == '__main__':
test(CORSRequestHandler, HTTPServer, port=int(sys.argv[1]) if len(sys.argv) > 1 else 8```

That's great! Also there is an even simpler method mentioned in this stackoverflow thread, without creating any line of code:

npm install http-server -g
http-server -p 3000 --cors
