ok, it helped to exclude workers from the build but I reverted code for my

functions/api/inquiry.js

endpoint to use Notion SDK

import { Client } from "@notionhq/client"

, so when I added the external package I got now another failed build with this statement

Are there some specifics I'm missing on how to import packages in functions or setup with next.js?
