openapi.yml examples do not appear in swagger

Question

I am working with apigenerator, I have a yml and according to https://editor-next.swagger.io/ everything is correct, the examples appear and everything is fine. But when I launch my project in swagger the examples do not appear. Also in the example of the result of the path get it appears not only in code 200 but also in errors 400 500. In the login, the examples do not appear in the corresponding fields nor in the definition part of the DTOs
