[Dúvida] CORS - Erro ao efetuar o requisito GET

Boa noite, Eu construí uma API Restful seguindo o curso da alura. Apenas troquei o JWT por JWT+Refresh token. No Postman, tudo funciona.

Porém, estamos criando (eu e o Eduardo que deu reply logo abaixo) um front-end vue e quando é feita uma requisição get com bearer token o seguinte é retornado:

A requisição get com erro e uma espécie de "cópia" dela com o método options com esse erro:

No 'Access-Control-Allow-Origin' header is present on the requested resource.
