1) I uploaded a .jsonl file containing 600 objects to Google Cloud Storage, but when I attempt to import it into Vertex AI RAG Corpus, it throws a cryptic 'KC' error. The error message is unclear and doesn't provide actionable details.
2) I uploaded another .jsonl file to Google Drive and shared it with the Vertex AI RAG engine service account, but when I try to import the file from the shared folder into the RAG Corpus, the folder appears empty. The file isn’t detected.
3) When I use the "Create Prompt" tab in the Vertex AI UI to query my vectorized data, it returns results along with chain-of-thought reasoning and citations. Will I get the same chain-of-thought style output (reasoning + citations) when querying the RAG system through the Vertex AI SDK or API?
