Steem-Python: AttributeError: 'bool' object has no attribute 'close'

in #utopian-io • 6 years ago

Project Information

Expected behaviour

App Continues to stream posts after this is caught (stopped catching it to get the stack trace) but with try-except, it just freezes upon this error occurring.
Hoping that there is some way to restore the connection, at the same point it left at

Actual behavior

The program hangs after the crash and doesn't continue to collect posts from the blockchain (or other data for that matter)

How to reproduce

I think it may have something to do with my internet, as it is rather slow!
Just stream the blockchain as so:

steem = Steem(nodes=["https://api.steemit.com"],keys=['postingkey'])
blockchain = Blockchain()
stream = map(Post, blockchain.stream(filter_by=["comment"]))
  • App version: 1.0.1
  • Operating system: Ubuntu 16.04.3 LTS Xenial running inside of WSL
  • Python Version: 3.6.5

    Hello @cadawg the issue could nor be replicated in my Ubuntu 16.04.3 LTS as you can see the pic below :

    After checking in the logcat you provided , i believe there is actually something wrong with your network as it shows time out.
    Anyway thanks for the contribution if the issue still shows ,you could submit it to github .
