Firestore doesn't allow to upload dictionaries. ValueError: One or more components is not a string or is empty

Question

伙计们。我需要使用 Firestore 上传字典。我的密钥可以使用，但我不知道为什么我无法上传此特定文档。

该项是字典，格式如下：

{
        "1": {
            "Fecha": "20220222",
            "Visitante": "########",
            "Visitado": "#######"}
}

函数：

def json_to_firestore(self,item):
    fecha = (self.auth_data["fechaDesde"]).replace("-","")        
    x = db.collection("Congreso")
    y= x.document(fecha)
    y.set(item)
    return True


Traceback (most recent call last):
  File "D:\CyberProyectos\ElTerrorDeLosPoliticos\v1\Scraper\Congreso\scraper.py", line 119, in <module>
    x.json_to_firestore(item)

    y.set(item)

将字典保存为 json，然后读取文件并将读取的文件上传到 firestore 成功了！
