• I'm using Version 0.17.230718.1-preview.
• Following the example from here - Example 17
• When calling the method GenerateMessageAsync on AzureChatCompletion object, I get the above error message. Below is my code

_chatRequestSettings.MaxTokens = maxTokens; _chatHistory.AddMessage(AuthorRole.User, prompt); string reply = await _chatGPT.GenerateMessageAsync(_chatHistory, _chatRequestSettings).ConfigureAwait(false);

To Reproduce Steps to reproduce the behavior:

1. Update nuget package to the latest version
2. Follow the example 17 to generate messages
3. See error

Expected behavior The response from Azure OpenAI is returned.

Platform

• OS: Windows 11
• IDE: VS 2022

Additional context I tried with ChatCompletionsAsync method too. Got the same error. Below is the exception detail -

Got the answer from Discord.

If referencing the Azure.AI.OpenAI package in the same project, beta 6 has a breaking change that’s incompatible with the current version of SK. Either downgrade to beta 5 or wait for the next SK release which updated to beta 6.
