you are making an XHR call that is resulting in a 500 from the server — Agney, Mar 21 '20 at 19:36

Use promise.catch clause or a try/catch block to handle server errors in your promise callbacks.

I think that the error is coming from the java API, in the console this is the error "JSON mapping problem: java.util.ArrayList[5]->com.ravtecnologia.desafio.models.Grupo["atividades"]; nested exception is com.fasterxml.jackson.databind.JsonMappingException: could not extract ResultSet (through reference chain: java.util.ArrayList[5]->com.ravtecnologia.desafio.models.Grupo["atividades"])" – Antonio Fabricio Mar 21 '20 at 23:06
