Type with the container name

Container name has a typo after some copy/paste. It's called "order-service" on this page, while on another page describing use of managed identity the same container name was correctly changed to "ai-service": https://learn.microsoft.com/en-us/azure/aks/open-ai-secure-access-quickstart.
