I have a map screen where when I click on the button to draw a polygon nothing happens on the map. Is there any issue in my code files?

I am listening to onNewBannerInstructions to show the instruction text and image on our custom view, without using any of Mapbox UIs. When onNewBannerInstructions is called, I check the components of the primary instruction and the image URL is null. How can I get the image for the instruction?
