How do I use Azure AI Foundry with Power Automate

I am tryign to use this connector: https://learn.microsoft.com/en-us/connectors/azureaifoundryinference/#create-a-chat-completion

But no matter what I do it returns an error:

 "error": {

            "code": "404",

            "message": "Resource not found"

        }

I can't find any documentation on how to properly set up the connection in Power Automate, and despite copy/pasting the Target URI, API Key, and model deployment name and model name exactly as they appear in the foundry, Power Automate spits out the error. I've seen contradictory information on exactly what the "Target URI" value should be, but no variation I've tried has worked. Ready to pull my hair out on this one, any help would be greatly appreciated, thank you.
