Minimal example that reproduces the bug
npm i && node index.js
Navigate to http://localhost:4000/, open the sandbox and type the following query:
query {
books(first: "one", second: "two") {
title
author
}
}
Hovering the second argument of the query shows the following error message:
Unknown argument "second" on field "Query.books".
This is happening when a query has more than one arguments and one of them is deprecated.
It is then removed from the schema in the Apollo Studio explorer.
