Solution 1:[1]

You have a copyField rule that specifices CREATED_BY_NAME as the source column, but this column name does not match any defined field in your schema - thus, it isn't a valid copyField instruction.

Remove the copyField instruction that references CREATED_BY_NAME as its source (or change it to the correct field (or define the field) if it matches a requirement).
