The principal’s ACL role lacks the required permission on this type or row.
No policy grants the principal the needed permission (read/write/etc.), or a cell-level mask/compartment blocked it.
Grant the permission via the policy table, or request a role with the required scope. Use EXPLAIN POLICY to see which rule denied it.
Every RelataDB error carries a correlation_id (UUIDv7). Cite it when reporting — ops cannot trace the request without it. See reporting errors.
