Pulled from git to make sure that the web application to be modified is updated. Restored the backup database from Jarv and tested the web application, as per testing, an error is encountered when logging in, checked for the cause of the error, and found out that there is a problem in authentication, checked the pre-prod, but it has no error. Checked the database, and per checking, the fields that are causing an error existed in the database, even though the database is OK, restored another database backup and tested it again, and as per testing, it is now OK.
