Need help: TypeError: basePath?.replace is not a function at createActionURL (file:///app/node_modules/@auth/core/lib/utils/env.js:71:45)

Hi,
Our authentication system in SvelteKit TS app has stopped working, and we're encountering the following error. Everything was functioning well just a few days ago. Could you help us identify what might have gone wrong?
Thanks!
