JWTの検証を行いたいのですが、正しいTokenを入れてPostmanでリクエストを送ると、
Could not get any responseが出力されます。

具体的にはGET http://localhost:1323/jwt に
Authorization: Bear ... で不適切なトークンを入れたい場合。

json
1{
2    "message": "invalid or expired jwt"
3}

と返されますが、先ほどの通り、正しいTokenを入れると、Could not get any responseと返されてしまいます。

理想はDemoWithJwtが呼ばれるのですが、実際に呼ばれず。

原因をご教授願いたいです。<(_ _)>
