'WebSocketProtocol' object has no attribute 'requestHeaders'

[whs]

I've recently upgraded Channels to the latest version, and found that WebSocket broke:

2017-02-10 22:22:47,341 ERROR    Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/daphne/ws_protocol.py", line 62, in onConnect
    self.requestHeaders,
AttributeError: 'WebSocketProtocol' object has no attribute 'requestHeaders'

You can try this out: curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H 'Sec-WebSocket-Version: 13' -H 'Sec-WebSocket-Key: XXXXXXXXXXXXXXXXXXXXXX==' https://tmstreamlabs.cupco.de. Note that this URL is not in the routing configuration, so there is no application code. Valid endpoints also have this problem.

• Setup: Separate Docker containers (but same image) for daphne + worker communicating using another Redis container
• Daphne is behind nginx, which also strip SSL
• Library version:
  • Channels: 1.0.3
  • Daphne: 1.0.2
  • Django: 1.10.5
  • Twisted: 16.6.0
  • asgi_redis: 1.0.0
  • autobahn: 0.17.1
