unionAll gives TypeError: leftSelect.getSelectedFields is not a function

I'm trying to query 2 collections in the same query as the amount of collections might grow over time that I will check against I would want a scalable way and also use drizzles built in features, so I tryed this:

Note I'm using Payload CMS, so I don't have access to the schema files directly, actually got no clue if its db.schema or db.tables I should use.

Running these queries separately works great, just when I add unionAll I get:
[15:34:20] ERROR (payload): TypeError: leftSelect.getSelectedFields is not a function
    at /Users/livog/Documents/Projects/Payload.CMS/node_modules/.pnpm/drizzle-orm@0.29.0_pg@8.11.3/node_modules/src/pg-core/query-builders/select.ts:677:42

Code:
const db = payload?.db
const drizzle = payload?.db?.drizzle

if (!payload || !db || !drizzle || collectionsToCheck.length === 0) return false // This will be checked server side or we don't support it without drizzle.
const rows = await unionAll(
    // @ts-ignore
    ...collectionsToCheck.map(collection => {
      const andCondtions = [eq(db.schema[collection]['path'], path)]
      if (currentCollection !== collection) {
        andCondtions.push(ne(db.schema[collection]['id'], currentDocId))
      }
      return drizzle
        .select({ id: db.schema[collection]['id'], path: db.schema[collection]['path'] })
        .from(db.tables[collection])
        .where(
          // @ts-ignore // Todo: type checking
          and(...andCondtions)
        )
    })
  )


This is the documentation that I looked at which I feel like I replicated:

Any help is super appreciated!
