can not interpret error `unsupported operand type(s) for +: 'float' and 'str'`

while running a short loop I get an error I cant interpret:

$ ./dump_remote_janusgraph.py

Here is the loop:

async def dump_all(app):
    session = await app.session()

    async for msg in session.g.V():
        print(msg)

loop = asyncio.get_event_loop()  # pylint: disable=invalid-name

app = loop.run_until_complete(Goblin.open(  # pylint: disable=invalid-name
    loop, get_hashable_id=get_hashable_id, configfile=CONFIG_FILE))
app.register(BinaryPackage, Requires)

loop.run_until_complete(dump_all(app))

Maybe the response_timeout config parameter is not being properly parsed? Could you please post your config file?

[goern]

None... sounds about wrong... put a 100 in there?

scheme: 'ws'
hosts: ['localhost']
port: 8182
ssl_certfile: ''
ssl_keyfile: ''
ssl_password: ''
username: ''
password: ''
response_timeout: None
max_conns: 4
min_conns: 1
max_times_acquired: 16
max_inflight: 64
message_serializer: 'goblin.driver.GraphSONMessageSerializer'

[goern]

man oh man... thanks for you pair of eyes on my config file!

[davebshow]

It looks like you are using YAML, which I believe requires null instead of None. None would be parsed as the string 'None'. I would just leave this out of the config, and the response_timeout will default to None, unless of course you want a response timeout, which is probably desirable in a production environment. In that case, simply include the key in your config, and pass an int or float.
