Using Rancher 2.8.5 and trying to upgrade cluster rke2 (onpremise bare metal) from version v1.26.7+rke2r1 to version v1.27.14.  
The install is stalled because al bunch of jobs running Helm charts failed because of an incompatible version detected.

What can i do to fix this?

Example error from logging:
