Getting empty response from Azure OpenAI GPT4o

Question

I have created an instance of GPT4o on Azure and I am getting response like this always no matter what query I pass. I am using tool calling and GPT4o is working fine without Azure but when GPT4o on Azure is giving me below response.

ChatCompletionChunk(id='', choices=[], created=0, model='', object='', service_tier=None, system_fingerprint=None, usage=None, prompt_filter_results=[{'prompt_index': 0, 'content_filter_results': {'hate': {'filtered': False, 'severity': 'safe'}, 'jailbreak': {'filtered': False, 'detected': False}, 'self_harm': {'filtered': False, 'severity': 'safe'}, 'sexual': {'filtered': False, 'severity': 'safe'}, 'violence': {'filtered': False, 'severity': 'safe'}}}])
