GraphiQL not available when served behind a reverse proxy

[DiamondJoseph]

I have deployed glazed behind a reverse proxy, along with other services.

p46-blueapi.diamond.ac.uk/glazed/(.*) redirects to p46-glazed:3000/$1

I am able to fetch/load the UI at p46-blueapi.diamond.ac.uk/glazed/graphiql, but when graphiql attempts to fetch the schema it attempts to fetch it from https://p46-blueapi.diamond.ac.uk/graphql, not https://p46-blueapi.diamond.ac.uk/glazed/graphql

There may be a apiPath argument that may need to be exposed and configurable?
