Hi there,
I have a multi agent application, and I want to debug my agents through devUI. But after setting up all the config values like

1. AZURE_OPENAI_API_KEY:
2. AZURE_OPENAI_ENDPOINT: https://???-????????-dev.cognitiveservices.azure.com/openai/responses?api-version=2025-04-01-preview

I am getting below error (refer screen shot): Can someone please suggest something?
<class 'agent_framework.azure._chat_client.AzureOpenAIChatClient'> service failed to complete the prompt: Connection error. (Code: server_error)

You're passing in a Responses API endpoint. Is that your intention, or do you want to use the chat completion API?

Yes, this is working fine when I am calling the agent directly.
But it is not working in devUI.
Let me know if I am doing anything wrong...

Interesting that it's working fine with a single agent call. Normally it's configured like AZURE_OPENAI_ENDPOINT: https://???-????????-dev.cognitiveservices.azure.com. If you want to use the Responses API, you use AzureOpenAIResponsesClient versus the chat completion call via AzureOpenAIChatClient.

I guess we should start there: how are you configuring your agent -- which client are you using? If you can please provide that, then I can work on repro'ing the issue.
