Rails record update works locally but not in production

Question

Any reason why a simple update would work locally but not in production on heroku (the repos are identical, everything up to date)? In the logs below I can see the parameter to be updated is making it into the request, but somehow the sql output only updates updated at:

Video Update (3.1ms)  UPDATE "videos" SET "updated_at" = $1 WHERE "videos"."id" = $2  [["updated_at", "2018-01-07 20:54:51.465131"], ["id", 85]]

In Development the exact same code produces in the dev server logs:

Video Update (0.7ms)  UPDATE "videos" SET "imdb_id" = $1, "updated_at" = $2 WHERE "videos"."id" = $3  [["imdb_id", "566"], ["updated_at", "2018-01-07 20:09:28.366552"], ["id", 119]]

So an update is being made but without the parameter, even though the param is whitelisted and included in the request log. I'm not even sure what information to include with this question or where the problem is (rails, postgres, heroku).

My production log:

Answer 1

It worked after I restarted Heroku. Maybe it didn't restart after my migration.
