You're not properly accessing n. So use either n in the table:
    if not res then
        local params = {n = select('#', ...), ...}
        local newf = function() return f(unpack(params, 1, params.n)) end
        co = coroutine.create(newf)
    end
or n as an upvalue:
    if not res then
        local n,params, = select('#', ...),{...}
        local newf = function() return f(unpack(params, 1, n)) end
        co = coroutine.create(newf)
    end
