Description

While trying to create a VCF cluster with only the mandatory fields as per the VCF terraform document: https://registry.terraform.io/providers/vmware/vcf/latest/docs/resources/cluster,
the cluster creation kept failing with a "internal server error:500".
But after following this particular blog exactly with all the fields mentioned here: https://cybernils.net/2024/01/11/using-terraform-to-commission-hosts-and-creating-clusters-in-vcf/, then the VCF cluster creation was successful.
So logging this issue so that it could be fixed in the VCF terraform provider document.

Affected Resources or Data Sources

Resource affected is "vcf_cluster"

Terraform Configuration

Attaching the word doc file which contains the main.tf and variables.tf terraform code copied.

Expected Behavior

Expected Behavior: The vcf_cluster creation should have been successful with only the required mandatory fields as mentioned in the VCF terraform doc link: https://registry.terraform.io/providers/vmware/vcf/latest/docs/resources/cluster

Actual Behavior

Actual: The vcf_cluster creation fails when we give only the required fields as per the VCF terraform doc link.

Steps to Reproduce

1. Create the main.tf and variables.tf file strcitly following the VCF terraform doc link: https://registry.terraform.io/providers/vmware/vcf/latest/docs/resources/cluster providing only the mandatory fields and omitting all the fields mentioned as 'optional' in the above doc link.
2. ON executing the 'terraform apply' command, the vcf_cluster creation errors out on the console with "internal server error code 500" and the API execution fails to start. There is no logging in the logs.

@cmsriram I replicated the scenario using the configuration you uploaded. I only modified the entity identifiers and names.
My cluster was created successfully. I'm attaching the console output for reference.
