TypeError: Function.prototype.apply was called on undefined, which is a undefined and not a function

Describe the bug

Hi, I just upgraded my system and I now get an error when running my project. I'm not 100% sure that this is an issue with routify itself, but the problem disappears if I remove routify from the build process so I think it's worth bringing it up here.

Reproduction

Install node (I believe I had v20 installed previously, so likely 21.x.x will reproduce this). Download the routify-starter template. npm i then npm run dev.

This seems to be the issue: https://github.com/roxiness/routify/blob/master/lib/utils/middleware.js

I don't know if there's a way of solving it. If not, we have to consider R2 to be incompatible with Node 21.

[ThatCoolCoder]

By R2 you mean routify 2.x?

[jakobrosenberg]

Yes. 👍

Had this same issue, upgrading to node v21.7.0 or above fixes the issue for me.
