Uploading picture via API: file path to URL

Hello Guys,
I am attempting to upload a picture via API and it seems that I tried all the possible options. Basically I think the local path needs to be somehow converted to URL, do you guys know how to do it?
usually my API can handle file URL and I thought it would work with URI as well but both name, file, etc does not work with app gyver.

i am trying to upload it to Xano if anybody managed to do it…
