Resolution

• This issue is resolved in VMware Cloud Foundation 9 and later, available at Broadcom downloads.
  If you are having difficulty finding and downloading software, please review the Download Broadcom products and software KB.
  
  
• For vCenter Server 8.x or earlier, this warning message can be safely disregarded, as the support bundle is still generated successfully despite the error.
