Firestore python查询抛出ValueError：路径`number-field`未消耗残留物：-number

Question

我是第一次玩 Firestore，我使用的是 Python 3.9.5

我已经成功地将数据添加到 python 中的数据库中：

        addDoc = db.collection('My-Collection').document()
        addDoc.set(val)

其中 val 是一个 json 对象。

但是，当我尝试在 number-field 上查询集合时：

docs = db.collection("Keno-Games").where("game-number", "==", 373).stream()

这是从 Firestore 控制台查询创建器复制的，它确实可以工作，但是当我尝试在我的 python 代码中使用它时它没有。错误是：

Traceback (most recent call last):
  File "/Users/timbolton/Desktop/kenoApi/kenoFirestoreIngest.py", line 21, in <module>
    docs = db.collection("Keno-Games").where("game-number", "==", 373).stream()

    raise ValueError("Path {} not consumed, residue: {}".format(path, path[pos:]))
ValueError: Path game-number not consumed, residue: -number

固定：

根据Documentation - Constraints on Field Paths，字段路径不能包含- 字符
