What happened?

in one of the cosmo releases broke introspection for fields marked @deprecated. In general, introspection is sometimes delusional.

Description

we use graphql-codegen to collect schematics from the router, but when we try to upgrade to the latest versions of the router, the fields marked @deprecated disappear and the playground breaks.

graphql-codegen sends queries like this

query IntrospectionQuery($a: Boolean = true){__schema {queryType {name} mutationType {name} subscriptionType {name} types {kind name description fields(includeDeprecated: $a){name description args {name description type {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name}}}}}}}}}} defaultValue} type {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name}}}}}}}}}} isDeprecated deprecationReason} inputFields {name description type {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name}}}}}}}}}} defaultValue} interfaces {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name}}}}}}}}}} enumValues(includeDeprecated: $a){name description isDeprecated deprecationReason} possibleTypes {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name}}}}}}}}}}} directives {name description locations args {name description type {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name ofType {kind name}}}}}}}}}} defaultValue}}}}

the feeling that includeDeprecated in query is broken

Steps to Reproduce

https://github.com/flymedllva/cosmo-introspection-broken

Expected Result

To make things work as before, deprecated fields were included in introspection, and cli utilities for graphql (including those not yours, such as graphql-codegen) worked.
In general, I would like the router's introspection to be fixed, since you still have to use Apollo for it – #991 The problem still persists, the error has disappeared, but introspection gives out nonsense.

Actual Result

if at least one field is marked @deprecated, an error will occur.
if all fields of type/input are marked as @deprecated, then this type/input is removed from introspection.
The feeling that includeDeprecated in introspection is not working as expected
Playground is broken
Using introspection is useless now because it gives out nonsense
