• From the HCX Manager UI, under Activity Logs, the following error is observed: "JSONArray[0] not found"

Cause

This issue occurs when a second task to unextend a network is initiated (either manually or via HCX API/automation) while the first task is still in progress, causing the HCX UI to display the progress at 0%.

Resolution

This issue is resolved in VMware HCX 4.11.1, available at Broadcom downloads.

If you are having difficulty finding and downloading software, please review the Download Broadcom products and software KB.

Workaround:
Do not click 'Unextend' or 'Force Unextend' repeatedly, even if the job seems slow. Allow the job to fail gracefully on its own.
