As mentioned in omniauth/omniauth-oauth2#81 and #3, version 1.4 of omniauth-oauth2 has an issue with query params being broken. Previously it overrode the callback_url, but now it no longer matches, causing all callbacks to fail.
This patch should fix the functionality to allow maximum compatibility with other versions. It's basically what many other strategy authors have done. Hope that helps!
