Google bigquery 将@@error.stack_跟踪保存在表中以便记录

我正在google BigQuery中创建一个数据仓库解决方案。 我想做的是创建一个日志表，这样我就可以查看数据更改过程的结果。但也能够在不干扰程序的情况下查看出了什么问题

在脚本中，我引发异常以捕获错误，并使用单独的过程更新日志表。唯一的问题是我无法保存错误的@error.stack_跟踪部分。它是我想保存在字符串中的数组值。虽然我将用户数组_改为字符串（@@error.stack_trace，'-#-'）用于更改值，但它会在数组_改为字符串错误时不断遇到错误。 下面是我的过程和错误消息

我存储@@error.stack_跟踪的表字段是字符串类型

在此方面的任何帮助都将不胜感激
