I'm trying to build a chat bot for Teams. I followed the instructions here for first time setup:
https://docs.microsoft.com/en-us/microsoftteams/platform/build-your-first-app/build-bot
When I open the Chrome debugger from VS Code, it logs in and then says "Something went wrong. For more information, please visit aka.ms/teamsdocs". Ironically, that URL returns a 404 not found. This is the error shown in VS Code:
