BotFramework-Composer: Failed to publish bot with LUIS from behind a firewall

Describe the bug

I use the Bot Framework Composer on the Windows PC with a corporate firewall. I already set up proxy configuration as environmental variables below:

HTTPS_PROXY=http://11.22.33.44:3128
HTTP_PROXY=http://11.22.33.44:3128
NO_PROXY=localhost

So most communication has no problem, but publishing the bot with LUIS is always failed with getaddrinfo EAI_AGAIN error. The error message is below:

Sorry, something went wrong with publishing. Try again or exit out of this task. request to https://westus.api.cognitive.microsoft.com/luis/authoring/v3.0-preview/apps/import?appName=ToDoBotWithLuisSample-0(composer)-additem.en-us.lu failed, reason: getaddrinfo EAI_AGAIN westus.api.cognitive.microsoft.com

I think the cause is not to go through the proxy when communicating with the LUIS API. I think getaddrinfo should not be called on the environment behind a proxy.
