Error when trying to htmlify scratch project with lists

[MijiGamin1]

My project is this, and whenever I try to htmlify it, I get this message: Unexpected error: TypeError: Cannot read properties of null (reading 'click') at https://scratch-converter.vercel.app/htmlifier-offline.html:1183:55 Has anyone else gotten this issue? Can someone help?

Hmm, can you try using this website https://sheeptester.github.io/htmlifier/ and see if it works there? Note that currently, the project ID option is broken, so you will have to download your project as an .sb3 and upload it to the HTMLifier as a file

It seems the error occurs when it tries to communicate back with the main page:

Maybe there is some browser security getting in the way, but not sure. It could depend on the browser being used
