Shib Idp v4 & OIDC 2 upgrade error

[Michael Fey]

Hi all,

I'm trying to upgrade from Shib Idp v3.4.6 & OIDC v1 to Shib Idp v4.0.1 
& OIDC v2, according to

https://doku.tid.dfn.de/de:shibidp:upgrade#upgrade_von_346_oder_347

https://github.com/CSCfi/shibboleth-idp-oidc-extension/wiki/Installing-from-archive

https://github.com/CSCfi/shibboleth-idp-oidc-extension/wiki/Upgrading-to-v2.x

But after all I get the following error:
