I kinda have an issue with the search-based Message Extension. When I debug locally, my app works fine. After deploying the messaging extension on Azure and testing it in the Teams app, I can search for specific queries. The Message Extension gives me the desired results, up to here we are good to go. The Problem: After I select one of the delivered search results, the messaging extension does not return the adaptive card. The chat-box in Teams is simply empty.
Is anyone familiar with this issue?
