SDDC Manager upgrade to 5.1.0 fails with "Failed to fetch data - Tasks".

Products

• VMware Cloud Foundation

Issue/Introduction

If users hit this issue, they cannot see their tasks in the task panel, and upgrades from 5.0.x to VCF 5.1.0 are blocked. This can happen only for users who had, at some point, VCF 4.0 running, and it was later upgraded.

Environment

VMware Cloud Foundation 5.1.x

Cause

In VCF 4.0, cluster creation tasks would have a sub-task that had a missing description. VCF 5.0.x up to VCF 5.1.1 cannot handle such missing task descriptions when trying to get all tasks and fails.

Resolution

The troubleshooting steps requires validation and updates in SDDC manager database. Please raise a Case with Broadcom Support to seek further assistance.
