Share/publish Obsidian canvas with sharecanvas.io

Hi there, thanks for building this tool! It’s really cool. I build a lot of my canvasses with embedded text, and currently the share feature does not display any embedded text, even for my published site which I have provided a link to, so it should be able to find the source of the text. The attached screenshot is what it looks like currently. Thanks!

I’m getting empty boxes (per image below) as a few others have reported.
My publish site is just a regular one; no password protection (Welcome! - Fil's Commonplace Book - Obsidian Publish)
The canvas does look right when I view it in Obsidian.
I used publish.obsidian.md/fas-cpb/ as the site when configuring sharecanvas.

Can anyone suggest what I’m doing wrong?

@wkevwang thank you so much for this!
Any update on the open sourced version?

@wkevwang, I put in my publish link, but am getting the following issue
Application error: a client-side exception has occurred (see the browser console for more information).

If I don’t put a link, my canvas will show up but does not have any embedded links from my published page.
