We want to update code that fetches from threads or roles to appropriately also fetch roles.special_role so we can include it in the return object. For now, I will leave in the r.special_role = ${specialRoles.DEFAULT_ROLE} AS is_default since I'm intermediately leaving in the isDefault property in RoleInfo. Towards the end of the stack, I will remove this check alongside the property as mentioned in the Linear task.
This diff handles role-fetchers.js
