Also, it's possible to see the conversion between the style snake_case and camelCase in the attributes and errors, this happens because exists a convention that the fields in the JSON must be snake_case, and PSR-2 and PSR-12 suggest the camelCase for the names of attributes in the classes, then it's necessary a conversion. For this was used the Case converter lib.
