AzureException: NoneType is not iterable

[isha1701]

Hi. I am using the azureopenai guide through which is have set the following:

CAI_MODEL = "azure/gpt4.1"
OPENAI_API_KEY="dummy"
AZURE_API_BASE="something" AZURE_API_KEY="something" AZURE_API_VERSION = "something"
ANTHROPIC_API_KEY=""
OLLAMA=""
PROMPT_TOOLKIT_NO_CPR=1
CAI_STREAM=false

I have selected the model after launching CAI and am getting this error:

"argument of type 'NoneType' is not iterable
