Do you only get this error on the mobile site? Do you get this persistently, or does it only happen randomly and infrequently?

Yes, it is something we use :P

Do you only get this on the mobile site?

My suggestion is to use the desktop site instead. We are not planning to fix the mobile site - rather, we're planning to get rid of it after we work on making the desktop layout more responsive.

We will keep an eye on the error, it's not clear to me if anything specific is causing it. Right now, I think it is related to the lag since it started today. If you notice any pattern to this error, please let me know.

We've removed the code that was causing this error, so you shouldn't see it again. Locking as resolved (for now!!)
