Firebase storage upload files issues

Hi everyone I created an image save stream using “pick Image from Library” and “Firebase storage upload”.
The flow works correctly if I simulate the app from the web but if I try to do it from the phone, I get this error: “error was thrown because all of the file uploads failed”. Have any of you been there before and can you help me? Thank you so much!
I am attaching my workflow (screenshot)

has it happened to anyone?
