Where is error message on the remote worker?

I tried the following implementation

function do_work(f, jobs, results, args...)
    while true
        x = take!(jobs)
        result = try
            f(x, args...)
        catch e
            ErrorException(sprint(showerror, e))
        end
        put!(results, (x, result))
    end
end

But this do_work will not catch any exception is f is simply not defined on the remote process. What I was asking is simply how to catch the undefined f error.
