1) To reproduce, create the following structure:

A) Insert an image component

B) In its logic, after the Event "Component Tap", add a "Pick image from library"

C) In output at port 1 of "Pick image from library", add the "Resize/compress image"

D) In outputs of "Resize/compress image", add different Alerts for outputs ports 1 (successful) and 2 (error).

2) Test uploading an image. What happens is that you can pick up the image from the library but then there is an error (port 2) in the "Resize/compress image" function. This error occurs only in web, it works perfectly for android so my conclusion is that the "Resize/compress image" doesn't work for web.
