Springboot error while returning JSON

Question

I am using Spring Boot on my API. Spring has the ability to convert Javabeans automatically to Jsons when returning an object.

However, with this code (in my MODEL layer) I am having a Classcastexception.

public InfosUserLogado listaUsuarioLogado(TokenApp tokenApp) {
    ResponseEntity<InfosUserLogado> responseEntity = requester.doRequest(tokenApp, Constants.USER_AUTHENTICATED_URL, HttpMethod.GET, null);
    return responseEntity.getBody();
}

java.lang.Classcastexception: java.lang.String cannot be cast to me.package.toolsapi.model.users.pojo.Infosuserloaded
