AI image creator

I made one AI image creator and I want to share the picture it produces.
Can anyone help me find the way?
It says file not found

and why you set the image.picture to this api key?

I tried different variations and now this one, but it doesn't find the file.
I don't know what else to do

sharefile filename should be a absolute path, that means like /storage /emulated/0/....

Unfortunately, I don't understand what and how this is done.
With pictures I would probably understand, unless it is very difficult

Where do I find what is missing from here?

obviously it's a File component.

In which drawer do I find the makefullpath and scope?
