Amazon web services AWS cloudwatch insights错误类别查询

我有两个每天运行的bath作业，失败时通常会抛出两种错误：

“psycopg2.DataError”和“broadcastyearweek”

我想得到不同类型错误的失败次数

我曾尝试过类似的方法，但没有效果：

fields @timestamp, @message
| filter @message like "broadcastyearweek" or @message like 'psycopg2.DataError'
| parse "broadcastyearweek" as @category, "psycopg2.DataError" as @category
| display @timestamp, @message, @category
| stats count() as counts by @category
| sort @timestamp desc
| limit 1000
