      * Previously, when installing a cluster on {ibm-cloud-name} into an existing VPC, the installation program retrieved an unsupported VPC region. Attempting to install into a supported VPC region that follows the unsupported VPC region alphabetically caused the installation program to crash. With this release, the installation program is updated to ignore any VPC regions that are not fully available during resource lookups.

      Description of problem:

      When using IPI for IBM Cloud to create a Private BYON cluster, the installer attempts to fetch the VPC resource to verify if it is already a PermittedNetwork for the DNS Services Zone.
      However, currently there is a new VPC Region that is listed in IBM Cloud, eu-es, which is not yet GA'd. This means while it is listed in available VPC Regions, to search for resources, requests to eu-es fail. Any attempts to use VPC Regions alphabetically after eu-es (appears they are returned in this order), fail due to requests made to eu-es. This includes, eu-gb, us-east, and us-south, causing a golang panic.

      Version-Release number of selected component (if applicable):

      4.12

      How reproducible:

      100%

      Steps to Reproduce:

      1. Create IBM Cloud BYON resources in us-east or us-south
      2. Attempt to create a Private BYON based cluster in us-east or us-south
      

      Actual results:

      DEBUG   Fetching Common Manifests...               
      DEBUG   Reusing previously-fetched Common Manifests 
      DEBUG Generating Terraform Variables...            
      panic: runtime error: invalid memory address or nil pointer dereference

      Expected results:

      Additional info:

      IBM Cloud development has identified the issue and is working on a fix to all affected supported releases (4.12, 4.13, 4.14+)
