Local file system Path not recognized

My goal is to save an image to firebase storage, because the url (from instagram) " https://scontent-frx5-1.cdninstagram.com/v/t51.2885-19/s150x150/115805821_3683456148349790_7697682752840594727_n.jpg?_nc_ht=scontent-frx5-1.cdninstagram.com&_nc_ohc=w610BKEl0EUAX9PDPy0&edm=ABfd0MgBAAAA&ccb=7-4&oh=c95326281f1b1b28934a74c6cab20c5c&oe=6189B610&_nc_sid=7bff83 "
doesnt work in web it only shows up in the tester app, so i thought of saving the image in frb storage and using it from there.

To do that im downloading the image on the device, i then set it to frb storage and then i delete the image from the device.

my problem is that after downloading the image, when i go to put the path in a filepath variable, i get this

also if i go to save the image directly with Firebase Storage upload files Logic i get this again
