When running the tests in the PR, I get an error as below. I have a very basic cosmosdb environment setup.

 {\\\"Errors\\\":[\\\"A Container Vector Policy has been provided, but the capability has not been enabled on your account.

Could you tell me exactly what I need to run the tests? Thanks!

Sure, go to “features” tab under “settings” in Azure portal and there is “Vector Search for NoSQL API”. You can enable it there. After that the tests should pass 😊

@TheovanKraay Thank you for the PR. It looks good. I ran the tests, polished the code, and merged the changes upstream. We also needed to add the spring-ai-azure-cosmos-db-store module to the main pom.xml.
