Hi! While ingesting BQ data I keep getting many such `WARNING`s, not sure what they mean?

'[2023-06-05 07:27:39,530] WARNING  {datahub.ingestion.source.bigquery_v2.usage:854} - Unable to parse <class '
           "'google.cloud.logging_v2.entries.ProtobufEntry'> missing read principalEmail, missing query serviceData missing v2 jobChange for "
           "ProtobufEntry(log_name='projects/my-project/logs/cloudaudit.googleapis.com%2Fdata_access', labels=None, insert_id='-nant09dgh1m', "

@square-football-37770 From code looks like connector is trying to read event from bigquery log

_parse_bigquery_log_entry

, but event is None.
