When I subscribe to F.US.GCEZ20 data after a while I get errors like below at QUANT.DTC.Utils.GetMessageType Line 15:

"Newtonsoft.Json.JsonReaderException: 'Unexpected end of content while loading JObject. Path 'BidPrice', line 1, position 40.'"

The recieved string is "{"Type":117,"SymbolID":1,"BidPrice":1891".

The DTC has changed since 2018, so we need to update that, if that's what you're using here.

How did you compile and implement the protobuf for the SC DTC?

Hi There,

This is the error I get when I use your newest version:
https://prnt.sc/1g694lg

If I move on the var msg looks like this:
"Unexpected end of content while loading JObject. Path 'UnderlyingSymbol', line 1, position 271. processing '{"Type":507,"RequestID":110000000,"SecurityType":1,"MinPriceIncrement":0.009999999776482582,"PriceDisplayFormat":2,"CurrencyValuePerIncrement":10,"IsFinalMessage":1,"SecurityExpirationDate":1623110400,"RolloverDate":1623110400,"Symbol":"FGBLM21-EUREX","UnderlyingSymbol":'"

I did some research on this. It has nothing to do with the symbols. The JSON string message gets truncated. Roughly 1% of all messages are lost in my case.
Here is how my log looks like:

2021-07-23 15:01:27.0477451|Warning|ClientOnError|Message Type Unknown Not Supported. Message:{"Type":140,"SymbolID":8,"DateTime":1627045286759,"Price":25.32000160217285,

2021-07-23 15:01:27.1362853|Warning|ClientOnError|Message Type Unknown Not Supported. Message:"Quantity":1,"Side":2,"UpdateType":1,"NumOrders":1,"FinalUpdateInBatch":1}

Here you can see that the message is split into two parts. I have to make Visual Studio beak at every Common Language Runtime Exception to see the message itself.

This is how the error looks like:

PN:
I have rewritten the written the Protocol.MessageType GetMessageType(byte[] packet) to Protocol.MessageType GetMessageType(string str, LogX log = null) so it takes a string instead of byte[] but I use the same GetString(byte[] obj) method for conversion as you do.
