Can't I use `lnurl` npm library in Nextjs14?

Question

In the first Nextjs14 boiler project you start, use the

npm i lnurl

After installation,

API, just by importing 'lnurl', the following error occurs.

For reference, it works fine on the demo site Nextjs13 below https://github.com/jowo-io/lnurl-next-auth-demo

I think that lnurl cannot be used in Nextjs.

Just following sentence is failed in Nextjs14

import lnurl from 'lnurl'

I found a workaround.

Write your api in page router not app rounter

Not,
/app/api/blabla~

But,
/pages/api/blabla~

Just, it works^^
