406 response during deploy?

I’ve noticed a few 406 responses happening sporadically on our site. I couldn’t quite figure it out until today, when I noticed it exactly as I was doing a deploy on Heroku. I’m wondering if Turbo returns a 406 if the Websocket is closed and, thus, the browser requests straight HTML?

If that’s the case, what’s the preferred method of deployment in Turbo? Note: currently using Heroku.

Can you provide:

  • The code inside one of the actions returning this error?
  • A list of views associated with that action (e.g. create.turbo_stream.erb)
