Singlekey

[E020]

After clicking this link:
https://p9.authz.bosch.com/auth/realms/obc/protocol/openid-connect/auth?client_id=one-bike-app&redirect_uri=onebikeapp-ios%3A%2F%2Fcom.bosch.ebike.onebikeapp%2Foauth2redirect&response_type=code&scope=openid+offline_access&code_challenge=7rCEDESyEoc4-sUcH8wvy9PkzZ3CP8M74g3yCkrIZq8&code_challenge_method=S256&kc_idp_hint=skid&prompt=login&nonce=YHs-H3WQskgSY5NZBSIVpeNUV0IUHFs-nPaLU6LbaWM&state=mA1lRZXFOUFeoocBUGJSHaU0Pg6_VPNs1VfviUABPa4

I'm redirected to https://singlekey-id.com....
After logging in I end up with a page with the error
but not with code=THIS_PART in it.

What am I doing wrong?
