Q:

Heroku Issue When Editing Blog (Random Routing to Matchheight.js)

I have a very strange issue when editing a blog entry on my Heroku production site.  It works fine locally, but when I try to submit from the edit page on Heroku, it redirects back to the edit page (as the controller dictates for unsuccessful edits) with the following errors in the log:

I do use matchHeight.js in the app, but not on the blogs#edit or blogs#show page, so this is weird.
Finally, I did just update to Rails 5.2, so this could (but hopefully doesn't) have to do with that.
Can anyone see what's going wrong here?  It still has an issue when I try update fields in rails c!
UPDATE
As requested, here's what happens when I run heroku logs -t:
