src/meta/types/tests/it/cluster.rs line 57 at r1 (raw file):

    assert_eq!(
        info,
        serde_json::from_slice::<NodeInfo>(&serde_json::to_vec(&info).unwrap()).unwrap()

This test should assert the serialized bytes does not contain cluster_id or warehouse_id, since the struct declared as:

    #[serde(skip_serializing_if = "String::is_empty")]
    pub cluster_id: String,
    #[serde(skip_serializing_if = "String::is_empty")]
    pub warehouse_id: String,
