overrideJson

IAM policy document whose statements with non-blank sids will override statements with the same sid from documents assigned to the source_json, source_policy_documents, and override_policy_documents arguments. Non-overriding statements will be added to the exported document.

NOTE: Statements without a sid cannot be overridden. In other words, a statement without a sid from documents assigned to the source_json or source_policy_documents arguments cannot be overridden by statements from documents assigned to the override_json or override_policy_documents arguments.
