NestJS + Vite + Graphql, playground loads once but then immediately throws "Schema must contain uniquely named type" reproducible git repo inside

Question

I've been trying to get this combination working for a while and fiddled with versions & compatibilities issue until I've hit this brick wall.

The app works in production once you build it -- it appears to solely be a vite issue when running in development mode.

I've created a minium repository where the issue is reproducible: https://github.com/sebastiangug/nest-graphql-vite

The graphql configuration:

        const config: ApolloDriverConfig = {
          debug: true,
          playground: true,
          autoSchemaFile: 'schema.gql',
          sortSchema: true,
          path: "/graphql",
          cors: {
            origin: ['*'],
          },
        };

Even if the request is not Graphql related, when the second HTTP request hits the server, vite attempts to do something that causes that schema error.

This seems to be a problem unique to this combination of tools.
