O acesso a fetch em ‘[https://boostfloral.discourse.group/latest.json?order=default&ascending=false’](https://boostfloral.discourse.group/latest.json?order=default&ascending=false%E2%80%99) da origem ‘[http://localhost:3000](http://localhost:3000/)’ foi bloqueado pela política CORS: O campo de cabeçalho da solicitação api-username não é permitido por Access-Control-Allow-Headers na resposta preflight.
