lighthouse: Argument names in nested mutations conflict with non-relation methods on the model

Describe the bug I am using the Spatie Permissions package and there is a ‘guard’ field on the Role class. When I try to return that field with a query, it will run the Model::guard() method.

Expected behavior Return guard field from the database

Schema

#types
type Role{
    id: ID!
    name: String!
    guard: String
}

#Inputs
input AddRoleInput {
    name: String! @rules(apply: ["required"])
    guard: String
}

input EditRoleInput {
    id: ID! @rules(apply: ["required"])
    name: String
    guard: String
}

#Add Queries to Base Query
extend type Query {
    roles: [Role!]! @all
    role(id: ID! @eq): Role! @find
}

#Add Mutations to Base Mutation
extend type Mutation {
    addRole(input: AddRoleInput!): Role! @create(flatten: true)
    editRole(input: EditRoleInput!): Role! @update(flatten: true)
    #editRoles(
    #    ids: [ID!]! 
    #    input: EditUsersInput!): [User!]! @bulk(flatten: true)
    deleteRole(id: ID!): Role! @delete
    deleteRoles(id: [ID!]!): [Role!]! @delete
}

Additional context

This seems to be the method it is getting caught up on. I’m not sure if there is a way to check if the method exists only on the model child class.

    protected static function extractHasManyArgs(Model $model, Collection $args): Collection
    {
        return $args->partition(function ($value, $key) use ($model) {
            return method_exists($model, $key) && ($model->{$key}() instanceof HasMany);
        });
    }
