ESM directory import fails at runtime — ERR_UNSUPPORTED_DIR_IMPORT #113
Description
Bug Description
@chat-adapter/teams is "type": "module" and the compiled output in dist/index.js contains a bare directory import:
from "@microsoft/microsoft-graph-client/authProviders/azureTokenCredentials"
Node.js ESM does not support directory imports. This fails at runtime with:
ERR_UNSUPPORTED_DIR_IMPORT: Directory import '…/authProviders/azureTokenCredentials' is not supported
Update the import to include the full file path: "@microsoft/microsoft-graph-client/authProviders/azureTokenCredentials/index.js"
Or configure tsup to bundle this dependency so the bare import doesn't appear in the output
Steps to Reproduce
Create a new chatbot with the teams adapter
Expected Behavior
It loads the bot

Not loading the bot
