How do I debug apollo/server/client subscriptions?

Are there any mechanisms for debugging a subscriptions on the server side and also on the client side ?

Chrome has a networking tab and you can view wss connections there.
Log aggregation might make things easier, as well, such as elastic or datadog.

Sorry no I meant within the Apollo code base as I am trying to get type-graphql working with subscriptions and I cannot see what is going on.

I would check the docs for debugging options such as that, but I’ve never tried to interrogate the Apollo toolchain like that.
