I have a new error : DeviceCodeCredential.get_token failed: Authentication failed: AADSTS7000218: The request body must contain the following parameter: 'client_assertion' or 'client_secret'.

# result = await graph_client.chats.post(request_body)

loop = asyncio.get_event_loop()

loop.close()

print (result)

Hi @Michael Wilcox

Have you tried the Graph SDK?

# Code snippets are only available for the latest version. Current version is 1.x
from msgraph import GraphServiceClient
from msgraph.generated.models.chat import Chat
from msgraph.generated.models.chat_type import ChatType
from msgraph.generated.models.conversation_member import ConversationMember
from msgraph.generated.models.aad_user_conversation_member import AadUserConversationMember

# To initialize your graph_client, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=python
request_body = Chat(
	chat_type = ChatType.OneOnOne,
	members = [
		AadUserConversationMember(
			odata_type = "#microsoft.graph.aadUserConversationMember",
			roles = [
				"owner",
			],
			additional_data = {
					"user@odata_bind" : "https://graph.microsoft.com/v1.0/users('8b081ef6-4792-4def-b2c9-c363a1bf41d5')",
			}
		),
		AadUserConversationMember(
			odata_type = "#microsoft.graph.aadUserConversationMember",
			roles = [
				"owner",
			],
			additional_data = {
					"user@odata_bind" : "https://graph.microsoft.com/v1.0/users('82af01c5-f7cc-4a2e-a728-3a5df21afd9d')",
			}
		),
	],
)
result = await graph_client.chats.post(request_body)
