Unused Variable in generated.go

[herzadinata]

What happened?

Afer running gqlgen generate

In VSCode using gopls, I got this warning that display

unused parameter: sel

That is caused by sel param not used

// generated.go

...
func (ec *executionContext) marshalNBoolean2bool(
	ctx context.Context,
	sel ast.SelectionSet, // <= this part
	v bool,
) graphql.Marshaler {
	res := graphql.MarshalBoolean(v)
	if res == graphql.Null {
		if !graphql.HasFieldError(ctx, graphql.GetFieldContext(ctx)) {
			ec.Errorf(ctx, "the requested element is null which the schema does not allow")
		}
	}
	return res
}
...

What did you expect?

I need the VSCode warning to dissappear, it's annoying and messup development experience.
The variable should be used or removed, but I can't change that because it is an auto generated file.
But I can't exclude that from gopls either. I have tried. To elaborate, I opened a question about it on StackOverflow:

Minimal graphql.schema and models to reproduce

# GraphQL schema example
#
# https://gqlgen.com/getting-started/

type Query {
  character(id: ID!): Character
  pogues: [Character]!
  kooks: [Character]!
}

type Mutation {
  upsertCharacter(input: CharacterInput!): Character!
}

type Character {
  id: ID!
  name: String!
}

input CharacterInput {
  name: String!
  id: String
}

func (ec *executionContext) {{ . }}(ctx context.Context, sel ast.SelectionSet, v {{ $type.GO | ref }}) graphql.Marshaler {

And find an appropriate condition that will allow us to choose to select _ instead of sel in that template.
