To Reproduce

Steps to reproduce the behavior:

1. Run the root & skill bots as per the instructions from the sample readme
2. Start the bot framework emulator & connect
3. Choose the DialogSkillBot
4. Enter activity 3

Expected behavior

Error not returned

As requested by @v-kydela I tried commenting out the two calls to send_activity_trace in the skillbot & re-running the test - here & here.

The error still happens.

Hello @wonboyn, I couldn't reproduce this issue using v4.11.0 of the botbuilder packages and the latest version of this sample. I tried with clean installations of Python 3.7.9 and 3.8.7

With those configurations, the sample runs as expected. But I noticed that there's an error in the requirements.txt given that it doesn't include neither botbuilder-dialogs nor botbuilder-ai, which are necessary for the skill bot to run. There is a possibility that you might've been running the sample with those packages outdated. Could you please double check the version of all botbuilder packages that you used?

Please let me know if you keep encountering this problem.

Thanks for the reply @wonboyn. Running the scenarios again I realized that in my previous test I was using Python 3.7.9 and 3.8.7 only for the Skill bot, the parent was always running in 3.8.7. After testing running the parent in 3.7.9 I was able to reproduce.

This looks like a product issue (I will transfer this to the python repo in the following days) and we should fix it in the course of our current release cycle - 4.12.0.
In the meantime, a workaround would be to run at least your parent bot in 3.8 (you can leave the skill in 3.7 or 3.8).

Let me know if you have further questions.

@axelsrz Is this still on your radar?
