when customer uses dashboard to export slow.log or tidb.log. This error named common.bad_request isn't meaningful.
I'm gonna list two scenarios I met to show why
Dump slow queries failed because of priv limit.
Slow query download from the TiDB dashboard was failing due to OOM at tidb server, customer had to increase tidb_mem_quota_query for the download worked.
