Browsers and versions affected

All browsers.

Description

The POST to /join/ returns a JSON message, but the response headers indicate it is an HTML document.

Steps to reproduce

Open the browser's network inspector and join any room.

Expected results

The HTTP headers should contain:

Content-Type: application/json

Actual results

The HTTP headers contain:

Content-Type: text/html; charset=utf-8

hi, same problem, have you solved it?

For my usecase, I ended up having to "manually" decode the JSON payload, since the invalid Content-Type prevents me from using aiohttp's .json() method:

Possible workaround from https://stackoverflow.com/questions/48840378/python-attempt-to-decode-json-with-unexpected-mimetype:

Use response.json(content_type=None) to disable warning.

@tobiasfriden Thanks for the pointer, but I'm not really looking for another workaround - my current one works. What I'd like is for the webservice to return the correct Content-Type so that no workaround is needed!
