> In *UpdateLog*, {{RecentUpdates}} reads the entry of tlogs, and throughout the project the entry indexes for various operations are consistent, but odd in this part. As we included new entry in TransactionLog for CDCR, read operations in {{update()}} method of {{RecentUpdates}} throw error rightfully as elements are read from wrong indexes of tlog entry. The entry indexes of llog should be consistent throughout.
