Issue while getting data from email events


When I was trying to pull down all email events related data via api call I was not able to get complete set.
Normally we used to receive around 96L records today it has stopped at 16L records, and the error message was like below
JSON Input 3.0 - We can not find any data with path [$.events[*]]!
when json read around 16L records.

Anyone faced this issue today ?
