Hi @shivgos
Welcome to the Quick Suite community!
Quick Suite requires specific IAM configuration to connect to Redshift for datasets and dashboards, even if you can query directly via the console or Query Editor. This ensures secure, role-based access for direct query or SPICE modes. Your table access works there because console queries use your personal IAM permissions, but needs explicit data source setup.
Please refer to the following Quick Suite documentation and community post this might be helpful for you.
