To find out the list of replicated transaction, query the MSrepl_transactions table in distribution database. Copy the sequence number of the transaction (i.e., xact_seqno ) which entered the distribution database last.

SELECT top 1 
entry_time AS trans_entry_time_in_dist_db,
FROM distribution.dbo.MSrepl_transactions
ORDER BY entry_time DESC

Copy the xact_seqno from previous query and replace it in @xact_seqno_start below.

EXEC distribution.dbo.sp_browsereplcmds 
@xact_seqno_start = '0x0005B68700176AEC000C' 
--replace the xact_seqno from the previous query

You will be able to see the command that failed and debug further.

If you just want to see the error message or other queries that are useful to monitor and debug the replication issues, you can refer this blog post.
