Users get confused between app routes and API routes. Instead of hitting
/api, they append /app in the API call, which ends up calling the
dashboard controller and throws an error. To fix this, we added a check
to throw a 406 Not Acceptable for non-HTML requests. But Meta requires
Accept: \*/\* to return 200 for the integration to be accepted.
This change will only throw an error for JSON requests.
