Hi,

My attempt to delete a rack has been hanging for more than 24 hours. Does anyone know what can be done here?

Error: Unsupported Terraform Core version

Module system.cluster (from “…/…/cluster/aws”) does not support Terraform  
version 0.12.21. To proceed, either choose another supported Terraform version  
or update the module’s version constraint. Version constraints are normally  
set for good reason, so updating the constraint may lead to other errors or  
unexpected behavior.

ERROR: exit status 1
