エラーの解消方法がわからず、是非皆様のお力を貸して頂けると幸いです。

### 現状

タイトルの通り、リンクを押下すると画面に『Not found. Authentication passthru.』と表示される  
（画面：http://localhost:3000/users/auth/github）

dockerでのエラー内容

```

    ***-web-1  | Started GET "/users/auth/github" for 172.19.0.1 at 2023-07-13 14:35:23 +0000
    ***-web-1  | Processing by Users::OmniauthCallbacksController#passthru as HTML

    ***-web-1  | Completed 404 Not Found in 2ms (Views: 1.3ms | ActiveRecord: 0.0ms | Allocations: 278)
    
```

### どうしたいか

現状login画面で『GitHubでログイン/登録する』リンクを押下後、githubログインを行いたい

以下を参照して色々試してみたが上手くいかず。

### 補足

GitHub側での`Client ID`, `Client secrets`は設定かつ間違ってないかを確認済み。  
以下の設定  
Homepage URL : `http://localhost:3000/`  
Authorization callback URL :
`http://localhost:3000/users/auth/github/callback`

question
ruby-on-rails ruby oauth devise
devise + OAuth2で画面に『Not found. Authentication passthru.』と表示される
下記のサイトを参考にしOmniAuthがPOSTまたはGETメソッドのリクエストを受け入れるように設定をしたら無事に遷移しました。
