Whitelist_external_dirs error with HA run on Qnap

hey guys,

anyone has any idea what I need to put under the Whitelist_external_dirs if HA runs on a virtual machine.
as Home Assistant OS, I’m trying to use my old automation if someone opens my gate I will get an image to my telegram from the camera.

I’m trying to understand the path I need to add

did not work PWD this path show.

any help will be nice.

only /config/camera/ work
