Errors while fetching Futures historical data in IBKR

[apellicerep]

Hi,

I've tried to fetch historical data from a NQ future contract in IBKR and I couldn't. First thing,
Example contract:
val asset = futureContract( symbol = "NQ", month = Month.DECEMBER, year = 2024, multiplier = 20.0, exchangeCode = "CME", )

When function "tofutureContract" builds an Asset creates a futureSymbol as NQZ24 when it should be NQZ4, this quick change fixes it:

old: val futureSymbol = "$symbol$monthEncoding${yearCode.takeLast(2)}"
new: val futureSymbol = "$symbol$monthEncoding${yearCode.last()}"

Second thing, when I want to retrieve the data like so:

    val yesterday = now.minusDays(4)
    feed.retrieve(asset, duration = "1 D", endDate = yesterday.toInstant(), barSize = "5 mins")
    feed.retrieve(asset)
    feed.waitTillRetrieved()

I get an error:

java.time.format.DateTimeParseException: Text '20241119 08:30:00 US/Central' could not be parsed at index 9
	at java.base/java.time.format.DateTimeFormatter.parseResolved0(DateTimeFormatter.java:2108)

Could it be this date formatter? seems that has two white spaces betwen date and time but the time string been parsed has only one white space.
private val dtf = DateTimeFormatter.ofPattern("yyyyMMdd HH:mm:ss")

Btw, great project.

Hmm, this always had two spaces (at least for stocks). Which version of the IB API are you using?
