Any client passing a boolean value for this parameter will now be considered invalid per the spec. In practice, a boolean project identifier was likely never a valid use case, but generated clients or strict validators that relied on the `boolean` variant being allowed may break.","2026-06-29T23:00:37.053Z"]
