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.

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: join(process.cwd(), 'src/graphql.ts'),
          cors: {
            origin: ['*'],
          },
        };
