A while back we got an email from Google saying they would move all our Firebase Analytics data in BigQuery to a new table and a new schema. Fair enough.
A couple of days ago, the change was made. But the problem now is that we only see null events in our <project>:analytics_xxxxx_.events_<date>
table. The events are correct in the intraday table, but for the last three days we only have null values in the events table. Anyone else seen this? Did we do something wrong or is it a bug with Google BigQuery?
I guess that you used the script they sent you for importing from Firebase. This is a known issue, and in some cases the script breaks the schema and that's probably why you are getting those null values.
I would recommend to reach Firebase Support [1] and they will help you solve this.
EDIT: I saw this other question posted and answered by a Googler that may be of help [2]
