SA permissions needed to run the RAG example

[jhammarstedt]

I've been trying to run the RAG example using the VertexAiRagRetrieval in our cluster (not hosted on google). It works fine locally but I keep getting:

google.genai.errors.ClientError: 400 INVALID_ARGUMENT. {'error': {'code': 400, 'messag │
│ e': 'Request contains an invalid argument.', 'status': 'INVALID_ARGUMENT'}}

I can run other examples (like the llm-auditor) that uses google_search tool so my guess is that it's an access issue. But I've been trying to give it all possible stuff but can't get away from the error. Any help here is appreciated.

I have tried Vertex AI admin, Storage object user, service user consumer, Discovery Engine Service Agent, Vertex AI RAG data service agent and a bunch of others

Solved, the roles were correct but something had happened to my RAG corpus input, so no problem here
