Bigquery JSON-不允许嵌套数组错误疑难解答

这里是bigquery的新成员。我一直在关注如何创建一个空模式，如何对json数据执行bq加载作业，以及如何处理在bq加载作业期间收到的每个错误消息

有一条错误消息给我带来了一些麻烦，除了这是一个嵌套数组错误之外，关于该消息的详细信息没有太大帮助

Error while reading data, error message: JSON table
encountered too many errors, giving up. Rows: 1; errors: 1. Please look into the errors[] collection for more details.
Failure details:
- Error while reading data, error message: JSON processing
encountered too many errors, giving up. Rows: 1; errors: 1; max
bad: 0; error percent: 0
- Error while reading data, error message: JSON parsing error in row
starting at position 0: Nested arrays not allowed.

下面是一个JSON文件，我使用它根据成功创建的模式创建了一个空表。这样，我假设这个数据模式是有效的，但是当我尝试用我的数据加载作业时，我得到了上面的错误

有人能给我指出一个正确的地方来寻找我为什么会犯这个错误吗？“标记”子字段中的数组是否违反此“嵌套数组”规则？如果是这样，为什么bq mk语句会使用模式创建一个空表？我看到了bigquery的有效数据模式的例子，但在我的例子中不允许这样做

感谢您的指导。谢谢

事实证明，该模式是完全可以接受的（由用于创建表的'bq mk'命令测试）。错误由重复字段（数组）中的一个元素给出，如下所示

["1", [] ]

下次再做三次检查！

你能提供JSON文件的第一行吗？事实上，我刚刚算出了。我最终得到了一个值，它也是team_attributes->tags字段中的一个列表（这恰好是一个可接受的数组，因为它是显式定义的）。我将在下面更新我的答案并结束这个问题。谢谢！
