Subquestion query engine doesn't work with azure openai but works with open ai. I have raised this issue earlier here and also the bug on github issue where I received automated response to use 2023-07-01 preview api which I have used from start and still facing the issue. Can someone help me to actually completely resolve this issue as I am not expert to go and update the llamaindex code myself. Please help me in resolving this as this will be very helpful for my urgent work. Thanks
