Failed to fetch. Possible Reasons: Cors Network failure URL Scheme - firebase

Question

I trying to do a swagger documentation for an Express API and Firebase database, when I make request to my database in local with postman it work, but with the swagger interface I get this error:
Failed to fetch.
Possible Reasons:
CORS
Network Failure
URL scheme must be "http" or "https" for CORS request.
For my documentation I use swagger-autogen and swagger-ui-express
there is a example for the login endpoint:
const app = express();
const port = process.env.PORT || 8080;
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cookieParser());
app.use(
cors({
origin: `http://localhost:${port}`,
methods: ["GET", "POST", "DELETE", "PUT", "PATCH"],
credentials: true,
})
);
app.use(helmet());
app.use(morgan("combined"));
app.get("/", (req, res) => {
res.status(200).json({ message: "Welcome" });
});
app.use("/api-docs", swaggerUi.serve, swaggerUi.setup(swaggerFile, options));
swagger.js
const outputFile = "schemas/swagger.json";
const endpoints = \["routes/auth.js", "routes/menus.js"\];
