Unable to create a Multi-device Conversation

Question

I follow this intruction for Multi-device Conversation, but can't create a conversation.

Keep receiving error:

@Hoa Vu I tried the same code with my resource in West Europe and it works as expected. Have you used both CreateConversationAsync() and JoinConversationAsync() samples in your Program.cs? Based on the line number in your error message I think you have added both. Try only using the CreateConversationAsync() method first to run the sample and then create a conversation from [ https://translator.microsoft.com] and replace CreateConversationAsync() with JoinConversationAsync()

Also, the parameter in your request to create a conversation seems to use en-US as from language and en as to language. Try to use different languages as mentioned in the sample in the config.

            string fromLanguage = "en-US";
            string toLanguage = "de";
