    "status": "404",
    "info": "Not Found",
    "errors": {}
}

You can pass a custom error message:

err_respond 404, key: 'user', message: 'Not present in database.'

{
    "status": "404",
    "info": "Not Found",
    "errors": {
        "user": "Not present in database."
    }
}

@user = User.new(user_params)
if @user.save
  # ...
else
  serialize_errors(@user.errors)
end

Will be generated (model errors):

{
    "status": 409,
    "info": "Conflict",
    "errors": {
        "username": "Username can't be blank.",
