Error in terraform Oracle Data Mover stack

[IcsX999]

Hello,

We have a problem with a stack creation and Oracle engineering team suggests us reach out to the team supporting this Terraform stack (https://github.com/oracle-quickstart/oci-hpc).
The logs are:

Can you help us to figure out the problem?
The log saids "an incorrect mount option was specified" but the field in stack creation was optional.
This run was with a zip archive provides by Oracle Cloud support.
Before we had other problems.

Thank you,
Gabriele
