Call to firebase Storage in Screen1.initialize

Hi, I have two procedure calls at startup in screen1.initialize, the first to a web component to see if I have an Internet connection and the second to upload a small picture in firebase storage.
While the first call gets executed normally, the second one seems to be not executed at all, because I don’t get any message in upload success or upload failed, and in fact, when I check firebase Storage, the file is not there.
here are the blocks I am using. Is there something that I am missing?
