We are noticing some posts where the previous revisions are not showing:
(there’s no text at all and notice the NaN on a post with 3 versions)
On the console I’m seeing a 500 error on /posts/X/revisions/latest.json .
On /logs I’m seeing the error below. This is on 2.8.6. We only noticed this after updating yesterday from 2.8.4, but I can’t guarantee it is related as we noticed this only in a couple of posts. I have tried rebuilt the container, but made no difference.
