text: Title: Azure Open AI support not working in 1.5.1
  Body: ### System Info
  
  Platform: Azure databricks
  Python version: 3.10.12
  pandas ai: 1.5.1
  
  ### 🐛 Describe the bug
  
  OS version:
  Python version:
  pandas ai: 1.5.1
  
  When changing from **1.4.10** to **1.5.1**, my code is not longer working. I am following the documentation and I changed **api_base* to **azure_endpoint** I am configuring the LLM as follows:
  
  llm = AzureOpenAI(api_token="my token", 
                      azure_endpoint="my endpoint", 
                      api_version="2023-05-15",
                      deployment_name="my deployment name",
                      )
  
  I tried different **api_versions** and I tried to set **is_chat** to true. I am using GPT 3.5 turbo with version number 0301.
  
  The reply I get from PandasAI, regardless of the prompt is 
  
  **_'Unfortunately, I was not able to answer your question, because of the following error:\n\nNo result returned\n'_**
  **Note that the same code works fine in pandas ai 1.4.10**
  
  Thanks in advance for the info and let me know if you need additional info.
