Normalize error

I have a postgress source and S3 as destination, When I am trying to sync data some time its syncing successfully but some time I get error written as “Failure Origin: normalization, Message: Something went wrong during normalization”.
Even i get error i can see files in destination getting created after every sync failure attempt.

Sync mode is full refresh and append.
I am attaching log file below.
