How can I avoid getting this error?

Looks like wsgi.version is a tuple instead of a string. Some change in the
server, probably.

@iancmcc Thanks for you reply :) I must admit I'm not sure what that means. Should I change something in the server and how?

Ian McCracken · Answer 3 · Tue Sep 06 2016 21:10:17 GMT+0800 (China Standard Time)

Naah, and also I was entirely wrong. Reading tracebacks on a phone leads to
mistakes :). The problem is that data is bytes being split with a string,
according to Google. If you change "\n\n" to b"\n\n", that may fix it.

Unfortunately, that was the first thing I tried (after Googling), but that results in a new TypeError:

TypeError: an integer is required and

TypeError: ('Not a bytestring', '<html><body><h1>200 OK</h1></body></html>'

Traceback (most recent call last):
  File "/usr/local/lib/python3.4/dist-packages/gevent/pywsgi.py", line 739, in _write_with_headers
    towrite.extend(data)
TypeError: an integer is required

During handling of the above exception, another exception occurred:

Still not anyone who can help with this error?

I will attempt to figure this out at my earliest opportunity.

Great! :) Would love to have ouimeaux working with Python 3.4 so I can integrate with my other smart home Python scripts.

I had a similar error when running under Python 3.4:

Traceback (most recent call last):

    mv = memoryview(data)

fix in my case was changing line 21 in ouimeaux/subscribe.py

from

SUCCESS = '<html><body><h1>200 OK</h1></body></html>'

to

SUCCESS = b'<html><body><h1>200 OK</h1></body></html>'

@fahrmairm thank you :) I'll try this at my earliest opportunity.

No error so far :) It appears to be working, but will continue testing.
