Prisma

Here is an error: ```Access to fetch at '...' from origin '<http://localhost:3000>' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.```

The server is on `graphql-yoga`, deployed to heroku (on local machine everything works great, no such issue). I tried to imprort `cors` package and use it like that: `server.express.use('/*', cors());` but it didn't help.

Pass `cors` options to your graphql-yoga <https://github.com/prisma/graphql-yoga#startoptions-options-callback-options-options--void----null-promisevoid>

<@U8X83GYSZ> I did it like that and it still works the same way:

```server.start(
  {
    cors: {
      origin: [/\.netlify\.com.*/, /localhost:.*/],
    },
  },
  ({ port }) =&gt; console.log(`GraphQL server is running on the port ${port}`),
);```
