with graphql + nestjs, vite seems to be adding to the schema on every request causing "Schema must contain uniquely named types" -- repository provided

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: ['*'],
          },
        };

import tsconfigPaths from 'vite-tsconfig-paths';

export default defineConfig(({ command, mode }: ConfigEnv) => {

              dynamicImport: true,
            },
            transform: {

            },
          },
        },
        appName: 'graphql-server',
      }),
    ],
  };
});

it works fine for me with vite 4 and latest version of this plugin:
