Trying to Implement Citation in Spring-ai along with vertexAI

[ery3k]

I am creating a Chatbot in spring-ai using VertexAI and i want to add citation to the response generated, but I am having probelms getting the cited sources from the ChatResponse object. I have set the .googleSearchRetreival(TRUE) and i am able to get answers to recent events, but when I look through the MetaData for citations, its being populated with the DefaultChatGenerationMetaData which does not contain the citation sources (ie. groundingMetadata)

Any help regarding this would be helpful
