A user has reported that sometimes (very randomly/intermittently) when they open a particular document library on their site, they are greeted with this message:

Sharepoint error message.png

I've done a bit of research and as near as I can tell "ko.computed" refers to some component of knockout.js. However, I have absolutely no clue what would cause this error to appear when opening up a normal, garden variety Document Library. Furthermore, it seems to be happening to just one person. There are about 20 users with access to the site/library, and the only one having this issue is the person who created the site. I suppose it could be a browser or cache issue, but it's so random that it's hard to know if using another browser "fixes" it or not.

I have never seen this before. No lookups on the library to other lists etc? 

 

Report it as a ticket in the Office 365 Admin centre as this looks like a code issue.

@Andrew Hodges , nope, no other columns in the library (aside from the library standard ones). The problem with reporting it is that it's terribly intermittent and we haven't found a way to reliably replicate it. In fact, it's ONLY happening (at this point) to ONE user in the group/site. As someone who's been on the receiving end of those support calls, I know that if they can't replicate it, they can't diagnose it and if they can't diagnose it, they can't fix it.
