    "code": 500,
    "reason": "refusing to parse login_challenge query parameter because oauth2_provider.url is invalid or unset",
    "status": "Internal Server Error",

  "updated_at": "2024-06-11T14:50:30.313677Z"
}

that's an ory kratos config value that should be set to connect Kratos to Hydra

thanks for answering, do you have any refrence to the related documentation? I think maybe it belongs to kratos.yml config file.. but what variable/key name?

oauth2_provider.url

is the key (or the env var version is

OAUTH2_PROVIDER_URL

)
