Legacy Firebase条件无法使用curl

Question

这个电话：

curl -X POST \
  -H "Authorization: key=AAAAx4uYEXU:...e8EEq9aCv-pGWXIfyCp_lUp28mY" \
  -H "Content-Type: application/json" \
  -d '{ "data": {
          "score": "5x1",
          "time": "15:10"
        },
        "condition": "'dogs' in topics || 'cats' in topics",
        "content_available": true
      }' \
  "https://fcm.googleapis.com/fcm/send"

导致此错误： 无效＆＃34;条件＆＃34;字段：仅支持＆＃39;主题＆＃39;条件

我直接从文档中复制了条件字段......我怎样才能让它工作？
