Error AsyncClient.init() got an unexpected keyword argument 'proxies'

The models internally use a library like httpx for HTTP requests. The proxies argument be incorrectly passed due to outdated or mismatched library versions.

• Check the model's dependencies in requirements.txt or pyproject.toml.

• If the dependency is locked by the environment, modify the deployment script or contact Azure AI Foundry support to adjust pre-installed library versions.

Azure AI Foundry might include a pre-configured script or template that assumes proxy usage and incorrectly adds a proxies argument.

Go to Foundry's Networking or Configuration section in the Azure portal. Disable Proxy Settings at Foundry Level

Add openai==1.55.3 to your requirements.txt to lock the version and avoid unintended issues caused by future updates please check this link and also refer this.
