@pawlikbartlomiej, For me, the information you’ve provided is a tad too little… Could you elaborate a bit more on:
- What are you trying to achieve?
- Are you talking about a form in frontend of backend (Admin)?
- Frontend: The Form plugin has its own File field that allows you to download a file into the folder of the page.
- Backend: There already is a download option in the page editor to download a file.
- I have no idea what information the screenshot is showing (and please don’t use screenshots…)
- Why are you using nodejs to create a Form page to download a file?
- Etc…
