Failed to subscribe to open interest on binance futures

See the error below:

This is weird because when I directly use cryptofeed to get the open interest it works as expected.
Using other exchanges like okex is ok.
It seems to fail only for binance open interest and just before the connection is initiated.

This should be fixed now @ph4z - but you'll need to use the latest version of cryptofeed from github
