Random error on init

[lucianobarcaro]

Hi, I'm trying to use this component, but, sometimes (really random - most of time, it works fine), when my app restarts, it gives me this error (gevent and asyncio, doesn't matter, tried both):

'AsyncioWebSocket' object has no attribute 'before_request_funcs' AttributeError("'AsyncioWebSocket' object has no attribute 'before_request_funcs'",)
  File "core/init/flask.py", line 74, in <module>
  File "/usr/lib64/python3.4/site-packages/flask/app.py", line 62, in wrapper_func
    return f(self, *args, **kwargs)
  File "/usr/lib64/python3.4/site-packages/flask_uwsgi_websocket/websocket.py", line 162, in register_blueprint
    blueprint.register(self, options, first_registration)

    self.record_once(lambda s: s.app.before_request_funcs

The code I used to init websockets is:

WebSockets = None  # Just load websockets if really needed
if bp_websockets:
    try:
        from flask.ext.uwsgi_websocket import GeventWebSocket as Sockets
        WebSockets = Sockets(app)
        for bp, prefixo in bp_websockets:
            print(' Registrando o blueprint WebSocket', prefixo)
            # The error occurs in this line.
            WebSockets.register_blueprint(bp, url_prefix=prefixo)
    except exception as E:
        from traceback import format_tb
        from sys import exc_info
        print('*** Erro ao configurar websockets', E, repr(E))
        print(''.join(format_tb(exc_info()[2])))
