It seems that there is an error in the aggregation for the query in BigQuery. You state that the aggregation groups data by the minute, but both the minute and timestamp attributes were included in the GROUP BY clause. You need to remove the timestamp attribute from the GROUP BY clause in order to aggregate by the minute. Otherwise, data is actually aggregated by the more granular timestamp attribute.
