Github issues should be used for bugs and feature requests. Use Stack Overflow for general “how-to” questions.

Version

What package version of the SDK are you using.

I use this container as build environment : mcr.microsoft.com/dotnet/sdk:3.1-alpine on Windows 10 OS build 19043.964 and use Bot framework emulator version 4.13 to test on windows.

Describe the bug

Give a clear and concise description of what the bug is.

When I run an emptybot in an alpine container, and test it with bot framework emulator, this error happens :

To Reproduce

Steps to reproduce the behavior:

1. sudo docker pull mcr.microsoft.com/dotnet/sdk:3.1-alpine
2. docker run --rm -it -p 8080:80 mcr.microsoft.com/dotnet/sdk:3.1-alpine sh
3. mkdir mybot
4. cd mybot
5. dotnet new -i Microsoft.Bot.Framework.CSharp.EmptyBot
6. dotnet new emptybot
7. dotnet run --urls http://0.0.0.0:80
8. Go to bot framework emulator
9. Open bot on this url : http://localhost:8080/api/messages
10. Look at the error and pull your hair.

Expected behavior

Give a clear and concise description of what you expected to happen.

When I do not use an alpine container and run an empty bot in windows, it works as expected and sends me a welcome message in emulator.

Running in alpine container should behave similarly, bot it doesn’t.
