@newbie_developer This issue needs to be reported on the botbuilder-python repo under issues. A recent request to update the version for msrest from 0.6.10 to 0.6.19 caused this dependency.
It looks like with the new question answering package this also becomes incompatible. Could you please raise an issue to check if the updated package can be published by the owners?
Also, I think the package can be installed from source by updating the requirements.txt file to msrest 0.6.21
The steps to install are on the readme file of this repo, if you need to use the package before a new version is published. Thanks!!
