A document should not be modified once it has been written to the output view. Making a copy of the document avoids issues. Change the loop to create a new wrapper Map

             wrapper = java.util.HashMap(in_doc)
             wrapper['query'] = "update iods_staging.{} set record_inserted = true;".format(item)
             self.output.write(wrapper)

Thanks again.
