I checked his redirect_uri, it sounds good: /authorize?redirect_uri=https%3A%2F%2Fapp.paris.happy-dev.fr%2Fadmin&response_type=id_token%20token&display=page&scope=openid&client_id=31de2a1107f54bbaad9333dd63c68113&state=BCZUXcR8na1KM6nPg3eWP5U5NfD78RGlMkhnSyTxNHA&nonce=zkhNMiI_EXWO2OU0Qr9IV2HzNu2prIn4bD6TUYtv1Lc&key=%5Bobject%20Object%5D
