Exception: 'LimitedStream' object has no attribute 'raw' when using Django 2.1.5

Using Django 2.1.5 I get the following exception:

Other Exception: 'LimitedStream' object has no attribute 'raw'
Traceback (most recent call last):
  File "/home/stefan/plexmap/plexmap-dev/venv/lib/python3.5/site-packages/ws4redis/wsgi_server.py", line 113, in __call__

Same problem here. Do you find something about it @stefancon ?

[Silent743]

I have same problem too.Have anybody idea about fixing it without downgrade Django?

[DaniilSezonov]

I think that the problem related with commit (django/django@08f78a4)

[DaniilSezonov]

with the next one

It seems I do something wrong but I cannot guess what

[jrief]

I never tested this library on Django-2 or later, so please be patient until I have some time to do so, or try yourself.
