Data ingestion failing when using higher Batch size

[Rupesh Choudhary <rupesh.7kumar.rc@xxxxxxxxx>]

Hi Team ,

We have been  trying to insert data (batch inserts) using a JAVA app which uses prepared statements  with parameterized queries to insert data .We are able to insert data with small batch size  however when we increase the batch size to a higher value data ingestion fails . We are using pgbouncer for connection pooling on database side which is running in session mode  and server_reset_query set to "DISCARD ALL" . Please suggest the how can we bulk load data with higher batch size .Below the error logs that we are getting from the application end.

Below are the logs from application :-
