Hi following the Guide I came across the issue with the part :
backups {

cloud_storage_container = "Storage-${var.domain}/my-terraformed-database-backup"
create_if_missing       = true

}
so while creating the DBCS it fails at this step and says:

Failed to configure Oracle Database Server...[ SCRIPT execution errors in [129.157.177.107]: *
getaddrinfo(3) failed for idcs-abcdefghijklmnopqrstuvwxyz.storage.oraclecloud.com:443 *

data/ORCL/control01.ctl" control_files = "/u03/app/oracle/fast_recovery_area/ORCL/control02.ctl" ]

For the vars I am using :
domain="idcs-abcdefghijklmnopqrstuvwxyz" (whatever circled in the image )
user="cloud.admin"
password="******"
endpoint=https://dbaas.oraclecloud.com

and for the main file I am using :
https://github.com/oracle/terraform-examples/blob/master/examples/oraclepaas/dbcs-instance-classic/main.tf
Let me know if I am missing something here or if things have got changed.

I see that API endpoint for storage :
https://gse*******.us.storage.oraclecloud.com/v1/Storage-*******
so in file it is Storage-${var.domain}/my-terraformed-database-backup which I think needs modification.
