javascript - 错误 : 3 INVALID_ARGUMENT: Cannot convert an array value in an array value in Firestore admin

Question

我正在尝试在我的 firstore 数据库中保存使用 twitter api 检索到的多个推文对象，但出现此错误:

Error: 3 INVALID_ARGUMENT: Cannot convert an array value in an array value

以下是样本 JSON对象:所有推文对象都与此类似

以上是给出错误的确切对象
在上面的代码片段中，参数线程是 array包含多个推文对象，就像前面描述的那样。
帮助将不胜感激。

Answer 1

您可以尝试透明地序列化/反序列化您的推文，以便:

在保存到 Firestore 之前将所有数组转换为对象

从 firestore

检索记录后，将所有键为数字的对象转换为数组

根据应该索引和查询的数据，您还可以使用 JSON.stringify()在 Firestore 不支持的结构的某些部分上。
