Binding a GraphQL Any field to a Go struct method returning *any doesn't work

[Tooni]

What happened?

the generation (go run github.com/99designs/gqlgen generate) errors out with

validation failed: packages.Load: /Users/tooni/qubit/gqlgen-todos3/graph/generated.go:2897:9: cannot use res (variable of type interface{}) as *any value in return statement: interface{} does not implement *any (type *any is pointer to interface, not interface)

because this invalid code is produced in generated.go

func (ec *executionContext) unmarshalOAny2ᚖinterface(ctx context.Context, v interface{}) (*any, error) {
	if v == nil {
		return nil, nil
	}
	res, err := graphql.UnmarshalAny(v)
	return res, graphql.ErrorOnPath(ctx, err)
}

What did you expect?

non-erroring code. maybe just &res in the return?

in v0.10.2, which is what i was trying to update from, this was the generated code for the same function

func (ec *executionContext) unmarshalOAny2ᚖinterface(ctx context.Context, v interface{}) (*any, error) {
	if v == nil {
		return nil, nil
	}
	res, err := ec.unmarshalOAny2interface(ctx, v)
	return &res, err
}

Minimal graphql.schema and models to reproduce

schema.graphqls

scalar Any

type ContentHaver {
  id: ID!
  content: Any
}

model.go

package model

type ContentHaver struct {
	ID          string
	ContentJSON *any
}

func (c *ContentHaver) Content() *any {
	return c.ContentJSON
}

gqlgen.yml
