Description

I have installed the latest version of R and IBrokers on Ubuntu 22.04.
I get the error mentioned in the title when I try to get a price quote for EURUSD currency pair

Expected behavior

Return the price quote for EURUSD pair.

Minimal, reproducible example

my_connection <- IBrokers::twsConnect(clientId = 0, port = 7497) # connecting to the paper trading account

isConnected(my_connection) # returns TRUE

# The next line was taken directly from the help documentation. Symbol was set to "EUR"
fx_pair <- twsCurrency(symbol = "EUR",
                                      currency='USD',
                                      exch='IDEALPRO',
                                      primary='',
                                      strike='0.0',
                                      right='',
                                      local='',
                                      multiplier='',
                                      include_expired='0',
                                      conId=0) 

is.twsContract(fx_pair) # returns true

reqMktData(my_connection, new_pair) # returns "TWS Message: 2 1 10285 Your API version does not support fractional size rules. Please upgrade to a minimum version 163."
