'NoneType' object has no attribute 'setdefault' IN python module

[sxp4u]

Here is my code, just same as what's in README.md

import bitmex

client = bitmex.bitmex()
result = client.Quote.Quote_get(symbol="XBTUSD", reverse=True, count=1).result()

print(result[0][0]['bidSize'])

then it incur an exception message like this:

Traceback (most recent call last):
  File "/Users/shi/PycharmProjects/crypoarbitrage/bitmex_api.py", line 3, in <module>
    client = bitmex.bitmex()

    proxies.setdefault(k, v)
AttributeError: 'NoneType' object has no attribute 'setdefault'

Do I config something wrong ? Is there anybody give me some hint ?

[sxp4u]

Actually, you can reproduce the issue using:

import bitmex

client = bitmex.bitmex()
# result = client.Quote.Quote_get(symbol="XBTUSD", reverse=True, count=1).result()

# print(result[0][0]['bidSize'])

the error message is the same:

Traceback (most recent call last):
  File "/Users/shi/PycharmProjects/crypoarbitrage/bitmex_api.py", line 3, in <module>
    client = bitmex.bitmex()
  File "/Users/shi/anaconda/envs/unibook/lib/python3.6/site-packages/bitmex.py", line 38, in bitmex

Have you solved the problem?I have the same problem.

[sxp4u]

This problem is associated with proxies. When I open Lantern, this problem appear, and when I close Lantern this problem disappear.

Have you solved the problem?I have the same problem.

I solve this problem by Quiting Lantern, and using OpenVPN build on my cloud server.

This seems to be a Bravado issue, see Yelp/bravado#401. You could try downgrading to Bravado 10.1.0, that worked for me.
