[amit12cool]

On running the sample https://github.com/microsoft/agent-framework/blob/main/python/samples/getting_started/declarative/microsoft_learn_agent.py I get the below error

agent_framework.exceptions.ServiceResponseException: <class 'agent_framework_azure_ai._client.AzureAIClient'> service failed to complete the prompt: Error code: 400 - {'error': {'code': 'invalid_payload', 'message': 'Invalid payload', 'param': None, 'type': 'invalid_request_error', 'details': [{'code': 'ValidationError', 'message': 'Not allowed when agent is specified.', 'param': 'temperature', 'type': 'error'}, {'code': 'ValidationError', 'message': 'Not allowed when agent is specified.', 'param': 'top_p', 'type': 'error'}], 'additionalInfo': {'request_id': '10f1c87bf01a1a0c8cc42e424d9b5064'}}}
