'Nonetype' object is not subscriptable error

[jtault]

Occasionally (every 10-20 votes or so) my bot fails with this error:

Traceback (most recent call last): File "./votingbot.py", line 113, in for c in steem.stream_comments(): File "/home/.local/lib/python3.4/site-packages/piston/steem.py", line 976, in stream_comments for c in self.rpc.stream("comment", _args, *_kwargs): File "/usr/local/lib/python3.4/dist-packages/steemapi/steemnoderpc.py", line 143, in stream for block in self.block_stream(_args, *_kwargs): File "/usr/local/lib/python3.4/dist-packages/steemapi/steemnoderpc.py", line 109, in block_stream head_block = props['last_irreversible_block_num'] TypeError: 'NoneType' object is not subscriptable

This is weird .. the props variable should have been filled from the API node .. I guess this is rather a connectivity issuer ..

It seems that my bot is able to handle lost connections successfully, so I'm not sure that is the problem. I'm not sure if it is related, but I also get these errors occasionally: Traceback (most recent call last): File "./votingbot.py", line 113, in for c in steem.stream_comments(): File "/home/.local/lib/python3.4/site-packages/piston/steem.py", line 977, in stream_comments yield Post(self, c) File "/home/.local/lib/python3.4/site-packages/piston/steem.py", line 100, in init post["_tags"] = meta.get("tags", []) AttributeError: 'str' object has no attribute 'get'

Also my voting function already catches broadcasting errors like so: def vote(c, weight): try: c.vote(weight, account) except BroadcastingError as e:
print("Vote failed...") print(str(e))
