Getting a "precondition failed" error

[fercom]

My bot is throwing an exception, It is published already, I cannot replicate the error and I have no Idea why it is happening.

Precondition Failed

The request that caused this error is: {"Properties":null,"Type":"message","Id":"4eswYGkzLapXSkmu","Timestamp":"\/Date(1474480550126)\/","ServiceUrl":"https://skype.botframework.com","ChannelId":"skype","From":{"Id":"29:1HfFfaW_8dCXP-oKg26IDPaNQbhlbthaMeSMhz3kUvJQ","Name":"vladstefansas || osu.ppy.sh/u/vladstefansas"},"Conversation":{"IsGroup":true,"Id":"19:9152b6ce8bb0467880517a14434dfcc4@thread.skype","Name":null},"Recipient":{"Id":"28:c0b2fa87-3625-43b2-be12-8eb1675818bb","Name":"MemeBot"},"TextFormat":null,"AttachmentLayout":null,"MembersAdded":null,"MembersRemoved":null,"TopicName":null,"HistoryDisclosed":null,"Locale":null,"Text":"ground squirrel meme","Summary":null,"Attachments":null,"Entities":[{"Type":"mention","Properties":[[[[[]]]],[[]]]}],"ChannelData":null,"Action":null,"ReplyToId":null}

However my Bot responds to the user and seems to work as expected, the error is captured by my log

I don't see SerializingDialogTask in your call stack - are you using the latest NuGet? https://github.com/Microsoft/BotBuilder/blob/master/CSharp/Library/Dialogs/DialogTask.cs#L420

I had the 3.1.0 version of botframework from nuget, I have updated, I am going to wait to see if the error goes away

Now it throws something else:

The call stack involves LuisService - are your subscription and model keys correct?

Do you have the type of the exception? You might consider breaking on thrown exceptions to see what it is.

I'm going to close this issue due to lack of response - feel free to open a new issue for further discussion.
