As the error states the page you are trying to open expects to recieve an object of the entity DateMonthlyFile. You are trying to open the page directly from another page without creating the object. To solve this issue, add a microflow to your button that perfroms a create object activity and create the DaeMonthlyFile object, then open the page with the new object as parameter. Don't forget to set the permissions on the microflow.
