[QA] Configured attribute preferred_username is not known

Seen with 2.2.0-rc.2 on core 10.9.1

Setup with kopano IDP via https://github.com/owncloud/QA/blob/master/tools/hetzner-deploy/deploy_openidconnect_test.sh

The OIDC section in config.php is according to https://doc.owncloud.com/server/10.10/admin_manual/configuration/user/oidc/kopano-setup.html#example-config-php

'openid-connect' =>
array (
'provider-url' => 'https://konnect-oidc-210-20220806.jw-qa.owncloud.works',
'client-id' => 'ownCloud',
'client-secret' => 'XXXXXXXXXX',
'loginButtonName' => 'Kopano',
'autoRedirectOnLoginPage' => false,
'redirect-url' => 'https://oc1091-oidc-210-20220806.jw-qa.owncloud.works/index.php/apps/openidconnect/redirect',
'mode' => 'userid',
'search-attribute' => 'preferred_username',
),

log in user aaliyah_abernathy with the Alternative Logins - Kopano button.
After clicking 'Allow' on the Kopano consent page, an error is shown:
The documentation suggests to change several fields 'if necessary' and gives an insufficient hint '(see identity provider configuration)' without a link.
- When editing the search-attribute to say name or email, etc. instead, the error message changes accordingly. All attributes that I tried are reported as is not known.
- Changing 'mode' to 'email' (as hinted at in the comment) has no effect on the error message.
- Adding a line 'scopes' => [ 'openid', 'profile', 'email', 'offline_access' ], /* seen in azure setup */ also has no effect.
