Hello,
In attempting to go through the basic tutorial, I end up getting the following error:
mappa.js:224 Uncaught TypeError: Cannot set property 'onload' of undefined
at o.value (mappa.js:224)
at setup (map.html:31)
at e.<anonymous> (p5.min.js:32)
at e.<anonymous> (p5.min.js:32)
at new e (p5.min.js:32)
at e (p5.min.js:32)
I updated the out-of-date code for loading the mappa js file, and, indeed, the console reads "Mappa loaded!" so I'm not sure what is causing the issue. It seems to be prompted y the command "myMap.overlay(canvas);" which is at line 31 of my map.html code.
Pasted below is the full text of the HTML file:
