Describe the bug

Currently, 500 errors from Azure OpenAI do not return a dictionary with key "error". This leads to a generic APIError/KeyError when it could attempt to return the message from the instead, which is more useful for end users

To Reproduce

Any request to Azure OpenAI that fails because of a non-specific Server Error

Example response:

{ "activityId": "123-123-123", "message": "Internal server error", "statusCode": 500 }
