I'm experiencing the same issue as #2855 but I don't manage to solve it (I guess that I'm doing wrong)

Steps to reproduce the behavior:

Expected behavior

I'd expect the cluster to be created without issues and with the ebs-csi-driver

Actual behavior

Apparently the data source tries to fetch the version and gives the error
