`function _format_user(user) {
return {
id: user.id,
display_name: user.display_name,
timezone: user.timezone,
first_day: user.first_day,
default_view: user.default_view,
default_calendar_id: user.default_calendar_id,
plan: user.plan,
plan_expiration: user.plan_expiration
};
}`

Start with src/api_server/routers/user.js and inspect the referenced _format_user function. The issue does not state what is wrong, what should change, or how completion would be verified, so the intended outcome needs clarification before implementation.
