There was a problem hiding this comment.
record.hasField and record.get will both search field in the internal schema, suggested changes.
Field sourceField = record.getSchema().getField(field.name());
if (sourceField == null) {
rec.put(field.pos(), null);
} else {
rec.put(field.pos(), record.get(sourceField.pos()));
}
