Description
The image generation API used on Azure OpenAI requires to specify the API version by appending an api-version query parameter to the endpoint URL. Added the environment variable IMAGES_OPENAI_API_VERSION with configuration functionality in the administration UI.
Added
Added the environment variable IMAGES_OPENAI_API_VERSION
Extended the administration UI to configure the optional API version for OpenAI image generations
Changed
When calling the OpenAI endpoint /images/generations endpoint a query parameter is appended in case the configuration IMAGES_OPENAI_API_VERSION is defined.
Additional Information
Please note that the image generation API call automatically appends the path /images/generations to the outgoing calls to the OpenAPI endpoints. When configuring the Azure Open AI URL, make sure to only configure the necessary host and path (without the /images/generations part). This behaviour hasn't changed with this PR. I'm just emphasising the lessons learnt.
