Since v0.0.6.3 I keep having this error published out so reporting as requested. I've included my log & script.

'NoneType' object has no attribute 'callback'
Got this exception from _on_tick_update. This is bug testing. Please report to https://github.com/slazarov/python-bittrex-websocket with this message

Hi @kierangraham, these error handlers were integrated as of 0.0.6.3 in order to capture a bug with thewebsocket library. However, the bug is not coming from these methods so I have removed them.

Uninstall the library and do a pip install git+https://github.com/slazarov/python-bittrex-websocket.git and reply back.

++ cheers for the exemplary issue posting :)

kierangraham commented

Errors are all gone now, thanks @slazarov 😄

A random question, I'm running this in Docker and suddenly is unable to connect to the socket. Something you've come across? Not sure what to put in a new issue that would help yet... I'm getting log output like this continuously:

The super weird part is that this works outside of Docker perfectly fine, which makes no sense to me...

slazarov commented

In the past I thought that the error is related to a dropped connection and I haven't edited it since.
The specific exception you are getting is from urllib3.contrib.pyopenssl import SocketError.

I haven't researched it thoroughly but it might be due to monkey patching.
Can you try running the code in a python3 venv?

kierangraham commented

That's the weirdest thing, I'm running using a pipenv environment which works fine on my local machine (outside of Docker) and fails with the error above when run from Docker.

Python isn't something I'm exposed to often so I could be missing or doing something pretty basic.

Nope also doesn't work for me 😞 – same error.

slazarov commented

Hey mate, I just ran the dockerfile myself. I am confirming the same error. For the time being, please run the library outside of docker. I will look into this as soon as I finish the reconnection handling. Best!

kierangraham commented

No worries, thanks for you help on these questions, really appreciate it :)

I’ll try to figure out what’s different as my small app worked a few weeks ago when I first set it up, if you find something new please let me know!

I’ll close this issue since what we’re discussing has nothing to do with the original issue.

slazarov commented

Great, thanks as well :)

kierangraham commented

@slazarov Hey 👋 , wondering if you'd any new news on this not running in Docker? I've tried updating and still the exact same result.

slazarov commented

Have you tried updating after the PR?

kierangraham commented

@slazarov Which PR? I've tried 0.0.7.0 & what's currently on master with the same results. When in Docker there's just a failure to connect to the socket. Dockerfile and code I'm running is the same as earlier in the thread only difference is I've updated the library.

slazarov commented

@kierangraham this is what I get:

$ docker build -t bittrex_socket . && docker run bittrex_socket
