I'm having trouble getting a translation prompt to work in my Azure OpenAI studio-deployed web app, despite it functioning in the chat playground. Can you assist?

Question

I have a web application deployed from an Azure OpenAI studio chat playground session that uses my own data source where the checkbox "Limit responses to your data content" is unchecked (False). When I use the prompt "translate the word house from English to Spanish", I receive a correct response (I get a translation) in the chat playground, but not in the web app. All "..._IN_DOMAIN" environment variables in the web app are set to false. Can you help me understand why the translation prompt is not providing a response in the web app, even though it works in the chat playground?

Prompt:

translate the word house from English to Spanish

Chat playground response:

I'm sorry, but as an AI text-based model, I don't have real-time translation capabilities. However, based on my training data, the word "house" translates to "casa" in Spanish. Please note that for more complex translations or context-specific translations, it's recommended to use a dedicated translation service.

Web App response:

The retrieved documents do not provide a translation for the word "house" from English to Spanish.
