Random error where mouse interaction stopped working

I saw this a few times yesterday, but I haven’t seen it since. I would get in this state where I could no longer create cards by clicking. And I couldn’t move cards.

The first TypeError occurs when clicking on a card (I think), and the second one that is repeated happens when moving the mouse cursor across the canvas.

In this state, I can hit Enter key and open the new card dialog.
I can fix this problem by reloading the browser.

again, no repro steps, so not super useful, but maybe code inspection may reveal something?

yup looks like a js null value issue, I’ll look into that thanks!

couldn’t repro this but I added some code that may theoretically prevent this. let me know if you see it again
