postgresql.conf contains errors; unaffected changes were applied


I have a postgres RDS instance with db engine version 12.17, RDS instance db.m5.2xlarge. It is having temp file of 12TB, so I was modifying the DB instance parameter group, temp_file option. But when I save and db instance tries to apply, I see error in postgres error. saying following. rdsdbdata/config/postgresql.conf contains errors; unaffected changes were applied.

What to do ?

This means that out of all the config changes that you made, the valid ones (ie. unaffected by detected errors) were applied by Postgresql.
