Error while parsing

[Falsen]

I get this error when trying to parse my demo:

Traceback (most recent call last):
  File "test.py", line 136, in <module>
    hlfinder.parse()
  File "test.py", line 45, in parse
    self.demo.dump()
  File "/root/python/demo/demoinfocsgo/demodump.py", line 146, in dump
    self._handle_demo_packet()
  File "/root/python/demo/demoinfocsgo/demodump.py", line 255, in _handle_demo_packet
    self._dump_packet(buf, length)
  File "/root/python/demo/demoinfocsgo/demodump.py", line 267, in _dump_packet
    callback(cmd, data);
  File "/root/python/demo/demoinfocsgo/demodump.py", line 187, in _handle_gameevent
    name = self.descriptors[gameevent.eventid][1]
KeyError: 27

What could be the problem?

I have encountered a similar error:

  File "<ipython-input-1-6275463898fe>", line 72, in player_spawn
    self.players[data.userid].is_alive = True

KeyError: 4

Any ideas?
