Problem when running example "historic_data" #130

I am trying to run the example at example/historic_data. I am using latest version from master and IB gateway version 972.

The only change I am making is using apple as the only contract to request historic data for:

contracts = {
    123 => IB::Symbols::Stocks.aapl

I am getting this error:

Traceback (most recent call last):
	10: from /Users/jorge/work/ib-ruby/lib/ib/connection.rb:357:in `block in start_reader'
	 9: from /Users/jorge/work/ib-ruby/lib/ib/connection.rb:284:in `process_messages'

/Users/jorge/work/ib-ruby/lib/ib/errors.rb:43:in `error': Unsupported version 123 received, expected 3 (IB::Error)

I can change the ticker id to 3 to remove the error (although that does not make much sense):

contracts = {
    3 => IB::Symbols::Stocks.aapl

And then, while no error raises, it does nothing either. The output is:

Connected to server, version: 137,
 connection time: 2018-11-20 12:35:25 +0100 local, 2018-11-20T12:35:25+01:00 remote.
No subscribers for message IB::Messages::Incoming::ManagedAccounts!
Got next valid order id: 1.
TWS Warning 2106: HMDS data farm connection is OK:ushmds

******** Press <Enter> to exit... *********

I didn't have trouble running other examples (market data, portfolio, real time data...).

I'd appreciate any tip you may have about how to fix this.

Thanks for your notice.
You are right. The HistoricalData-Message has changed.
In the recent API, the version-Field is gone.
ib-ruby complains correctly about the missleading value.

I wlll update an update after writing some later today.
