node-fs triggers build error with spago/esbuild

I am not sure whether this is a node-fs or spago problem, therefor i'm cross posting. Please close when this issue is not relevant for this repo.

Reproduce & error:

mkdir nodefssync
cd nodefssync
spago init
spago install node-fs node-buffer

now paste source code into Main.purs

module Main where

import Prelude

import Effect (Effect)
import Effect.Console (log)
import Node.FS.Sync
import Node.Encoding

main :: Effect Unit
main = do
  _ <- readTextFile UTF8 "blabla"
  log "🍝"

spago bundle-app --platform=node
node index.js

» node index.js
