Chat Playground is success , but when called from HTTP Request, got error error_code=OperationNotSupported error_message='The chatCompletion operation does not work with the specified model"

Question

I have a chat play ground on Azure Open Ai Studio, using my own data that retrieved from BlobStorage.

I can do the retrieval from Play Ground,

and then i called it from browser, using code that i have same as the example :

the model i use already gpt-turbo-16k

But when i called from http , i got error :

error_code=OperationNotSupported error_message='The chatCompletion operation does not work with the specified model, . Please choose different model and try again. You can learn more about which models can be used with each operation here: https://go.microsoft.com/fwlink/?linkid=2197993.' error_param=None error_type=None message='OpenAI API error received' stream_error=False

I have try to change the model to 16 k, and it's not working on both playground and httprequest, and also i try to change the api version as well, but it doesnt work on HTTP request, but still works on Chat Play Ground.

Please help ...
