Issue
Updates to Pega Platform™ 24.1.5 from Pega Platform versions prior to Pega Platform '24.1 fail.
Symptoms and Impact
In Pega Platform '24.1.5, the rules update fail during the Context Upgrade step. Logs show that pzQueueProcessRuleForGuardrails fails to trigger due to insufficient authentication. All direct updates to Pega Platform '24.1.5 from Pega Platform version 7.1.10 or earlier will fail on this step. There is a small risk of failure when updating from other source versions earlier than 24.1.0.
Solution
Update to a later release such as Pega Platform '26.1.
If an update to the latest Pega Platform '25.1 or '26.1 is not possible, you can perform a direct update to 24.1.4 first and following that you can carry out a patch update to 24.1.5.
