Firestore python查询抛出值错误：路径`numberfield`未使用剩余值：number

Question

我第一次使用Firestore，我使用的是Python 3.9.5

我已使用以下方法成功地将数据添加到python中的数据库：

        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控制台查询创建者复制的，它确实可以工作，但当我尝试在python代码中使用它时，它就不能工作了。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

固定的：

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