I’ve used Agent Builder to create a conversational agent and have integrated with Slack. The agent works perfectly in my Slack channel but does not display the final output or recommendation.

I am using Vertex Search API to build a generative search widget that searches through a repository of articles and generates a response to the user based on their query. The API is using unstructured data stored in a GCS bucket. The data is imported via a JSONL metadata file (also stored in the same bucket) that references the article files in the bucket and links things like the author and url of the article.
