Expected behavior

No error

Screenshots

given in each steps

Additional context

I believe this is same issue rasied in here : https://github.com/microsoft/BotFramework-Composer/issues/8891 and same work-around that set confirmation in skill, solve the issue as well. (but our use-case is broken).

but answer in above issue was concluded like it happen in 3 bot case and one bot is used skill and also skill consumer, but it is not in my case, it happen only with rootBot and skillBot without additional 3rd bot. So I need clarification on this issue or hope to get work around. I think this is more generic issue.

Hi @Seungchul-de If you do not have 3 bots (root->skill1->skill2), then this is not the same issue as 8891.

• Does this still reproduce if you remove the Repeat this Dialog action?
• This is with a local running root bot and skill, correct? Not deployed to Azure/cloud.

[Seungchul-de]

Hi @dmvtech 1) yes 2) yes.

[Seungchul-de]

@dmvtech for your reproduce, I create a sample here, issue.zip

you can reproduce issue as following Thanks

[dmvtech]

I have isolated the issue in that this happens with a Node runtime root bot and a C# skill. Will continue to investigate.

[dmvtech]

I am testing some other scenarios and will update shortly.

@tracyboehrer I did not get this with a dotnet root bot and a node skill.

Hello @ceciliaavila do you have any update on this issue?

Hello @ceciliaavila do you have any update on this issue?

Hi @axelsrz, we are currently working on this issue. We noticed differences in the conversation states between .NET and JS implementations. We'll let you know as soon as we have more information.

[ceciliaavila]

Hi @axelsrz, this is what we have on this issue: The error happens when a JS root bot connects with a skill that contains only one conversation turn. After coming back from the call, the next action seems to get lost, and the root bot tries to begin the skill again.

We debugged the code, comparing the execution with a .NET root bot, and found a difference in the BeginSkill action's state stored in the dialogOptionsData (in JS, the BeginSkill action is remaining as the active child dialog while in .NET it's the next TextInput action). This difference is causing the conversation state to be saved when it shouldn't, replacing the correct conversation state and causing the issue.

We could use some help to find the reason behind this difference to apply a fix. If you have time we could sync up to figure out how to continue.

As a workaround, we noticed the error doesn't happen when the skill dialog has more than one turn. Adding an input or an EndTurn action to the skill bot will prevent the error.

@munozemilio Closing as it was corrected by linked PR. Will require SDK release.
