IBPriceBar failed to decode double

[shial4]

I've tried to subscribe to ETH, using below method and utilising raw initialiser for your enums from values
marketData("ETH", interval: 5, secType: "CRYPTO", exchange: "PAXOS")

private func historicBarPublisher(
        for contract: IBContract,
        barSize size: IBBarSize = .minute,
        duration: IBDuration = IBDuration.continuousUpdates(60, unit: .second)
    ) throws -> Int {
        let requestID = client.nextRequestID
        try client.requestPriceHistory(
            requestID,
            contract: contract,
            barSize: size, // from raw time interval == 5
            barSource: IBBarSource.trades,
            lookback: duration // IBDuration.continuousUpdates(60, unit: .second)
        )
        return requestID
    }

IBPriceBar fails to decode double

will investigate
as a workaround:

var subscriptions: [AnyCancellable] = []

client.eventFeed.sink (
	receiveCompletion: { completion in
		print(completion)
	}, receiveValue: { anyEvent in	
		switch anyEvent{
		case let event as IBPriceHistory:
			event.prices.forEach{print($0)}
			print(String(repeating: "-", count: 30))
		case let event as IBPriceBarUpdate:
			print("update", event)
		default: break
		}
	}
).store(in: &subscriptions)
	
do {
	let requestID = client.nextRequestID
	let crypto = IBContract.crypto("ETH", currency: "USD", exchange: .PAXOS)
	// 5 minute history + updates
	let lookback = IBDuration.continuousUpdates(300, unit: .second) 
	let resolution = IBBarSize.minute
	let source = IBBarSource.trades
	try client.requestPriceHistory(requestID, contract: crypto, barSize: resolution, barSource: source, lookback: lookback)
} catch {
	print(error.localizedDescription)
}

I did run exactly the code you've suggested. with the result as shown below:

[stensoosaar]

With the most recent update I included this request into playgrounds market data page. Does it produce the same error?

[shial4]

yup, I use IB Gateway 10.19 from here
localised for AU

[stensoosaar]

I managed to reproduce the error earlier, but after using IBPriceBarHistoryUpdate instead of IBPriceBarUpdate for decoding, it seemed to vanish...

gateway 10.25
set region to Asia, time zone to Australia/Sydney
branch: main
playground page: market data

and the result:

This issue still persist for the given use case. when using IBDuration.continuousUpdates
