Logged on behalf of the customer:
Summary
When changing a group member’s type (e.g., from IPAddress to Generic) in an NSX policy group, Terraform plans the change as an in-place update but fails during apply with error 500336. The provider should mark type changes as requiring resource recreation.
Current Behavior
• Terraform plan shows the type change as an in-place update
• Terraform apply fails with: Error: Failed to update Group MANUAL-Tenable-scanners: Invalid Group Member type update. IPAddress type cannot be updated to Generic type. (code 500336)
Expected Behavior
Terraform should detect that changing a group member’s type requires destroying and recreating the resource, similar to how other providers handle attributes that cannot be updated in-place

Describe the solution you'd like

Modify the provider to mark the group member type attribute with ForceNew: true to ensure Terraform properly plans a destroy and recreate operation when the type changes
