Hi @YUUTA.INOUE-JPN,
I would recommend having a look at this related thread. You can tweak the xpack.reporting.csv.maxSizeBytes setting for the above steps, but I would advise caution in doing that.
You can also try another approach such as splitting the request into smaller batches using tools such as a Python script of Logstash plugins, both of which are in there referenced thread.
Hope that helps!
