just a workaround … in botframework.py:
@botframework_webhook.route("/webhook", methods=["POST"])
async def webhook(request: Request) -> HTTPResponse:
postdata = request.json
metadata = self.get_metadata(request)
if metadata is None:
metadata = {'name' : None}
metadata['name']=postdata['from']['name']
gives me the metadata filled: {‘name’: ‘xxx xxx’} seems a bug in botframework
