using demand control raises "TypeError: Invalid value used as weak map key" on startup

[n1ru4l]

Using the following gateway config with the docker container causes crash upon startup.

gateway.config.ts

export const gatewayConfig = defineConfig({
  demandControl: {
    maxCost: 1000,
    includeExtensionMetadata: true,
  },
});

docker run --name hive-gateway --rm -p 4000:4000 --volume $(pwd)/gateway.config.ts:/gateway/gateway.config.ts \

When commenting out the demandControl configuration, everything works as expected. It seems like it is only supported in the supergraph mode right now.

However, the documentation does not mention this limitation at all: https://the-guild.dev/graphql/hive/docs/gateway/other-features/security/demand-control. In addition to that I also think demand control should work in proxy mode.
