CORS issues even when origins specified

Not sure what I'm doing wrong here

export default buildConfig({
  serverURL: "https://beta.safsonline.com",
  admin: {
    user: Admins.slug,
  },
  cors: ["http://localhost:4200", "http://safsbeta1.safsonline.com", "http://safsbeta2.safsonline.com"],
  csrf: ["http://localhost:4200", "http://safsbeta1.safsonline.com", "http://safsbeta2.safsonline.com"],
  collections: [Admins, Users, Pages, Media, Documents],
  typescript: {
    outputFile: path.resolve(__dirname, "payload-types.ts"),
  },
  graphQL: {
    schemaOutputFile: path.resolve(__dirname, "generated-schema.graphql"),
  },
  routes: {
    api: '/payload/api',
    admin: '/payload/admin',
    graphQL: '/payload/graphql',
    graphQLPlayground: '/payload/graphql-playground'
  }
});

and in server

app.use(express.json());
app.use(
  cors({
    
    origin: ["http://localhost:4200", "http://safsbeta1.safsonline.com", "http://safsbeta2.safsonline.com"],
    credentials: true,
  })
);
