Can't export CSV file to a folder in app directory unless it is in the 'public' folder

Wappler Version : 3.5.6
Operating System : Win10
Server Model: NodeJS
Database Type: PostgreSQL
Hosting Type: Docker

Expected behavior

What do you think should happen?
I thought you could export a CSV file to a folder inside your app structure, event if it wasn’t in the public folder.

Actual behavior

What actually happens?

If i try to export to say app > exports > file.csv then i get the below error:

{"status":"500","code":"ENOENT","message":"ENOENT: no such file or directory, open '/opt/node_app/exports/historical_data.csv'","stack":"Error: ENOENT: no such file or directory, open '/opt/node_app/exports/historical_data.csv'"}

How to reproduce

Create a DB query
Create an export to CSV step
Select a filepath that is inside the app strcuture, but NOT in the public folder.

This is my step:

I have tried this with or without Overwrite and with or without the file existing. They all work fine if exporting to the public folder but not outside the public folder.
