Problems with Hetzner CSI 2.7.0

[loxy]

When I use the latest version I get problems installing Hetzner CSI correctly. Recently, there was a release of that lib:
https://github.com/hetznercloud/csi-driver/releases/tag/v2.7.0

But it cannot pull corresponding docker images as they are not published, see:
hetznercloud/csi-driver#611

When I now try to use version 2.6.0 via hetzner_csi_version = "2.6.0", it shows:

error: accumulating resources: accumulation err='accumulating resources from 'hcloud-csi.yml': missing Resource metadata': must build at directory: '/var/post_install/hcloud-csi.yml': file is not directory

Any hints. What I'm doing wrong? It happens on completely fresh install...
