Hug bug in 2.5.0 where POST requests don't never return

Dockerfile

FROM python:alpine

RUN pip3 install hug==2.5.0

WORKDIR /app

EXPOSE 5454

CMD hug -p 5454 -f /app/main.py

main.py

import hug

@hug.post("/test", output=hug.output_format.json)
  def post(body, response):
      print(body)
      return {'message': 'ok'}

Notes.md

When making a post request to Hug (v2.5.0), i never get a response. If I Ctrl-C the hug process, i get the following trackback...

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/wsgiref/handlers.py", line 137, in run

KeyboardInterrupt

Version 2.4.9 seems to work just fine.

Reproduction steps

1. Build the docker image

docker build -t hug-bug --no-cache .

2. Run hug

docker run --rm -it -v $(pwd):/app -p 5454:5454 hug-bug

3. Curl our hug service

curl -H "Content-Type: application/json" -X POST -d '{"foo":"bar"}' "localhost:5454/test"
