Uncaught mysqli_sql_exception: Duplicate entry

[TwinMist]

Just migrated to php 8.3 was using 7.2 before with no issues.
i have multiple inserts within the same script which somehow is causing duplicated inserts from another part of the script
on this error the table does not even have primary key date this was a insert from another part of the script
any ideas?

Could it perhaps be a UNIQUE constraint (possibly combined with a default value of NOW()) on one of the columns which you're bulk-updating?
