Issue

After upgrading to Analytics Plus build 6300, scheduled activities across the application may fail to trigger.

As a result, configured schedules do not execute automatically, preventing several background operations from running as expected. This may affect features such as:

• Scheduled data synchronization

• Scheduled email reports

• Backend database cleanup

• Other scheduled maintenance tasks

These operations rely on the application scheduler, and when the scheduler fails to execute, the configured activities do not run automatically.

Error Observed in Logs

The following error can be found in the application logs:

Root Cause Analysis (RCA)

During this upgrade:

• The MickeyLite framework was upgraded from MICKEYLITE_4.44.1 to MICKEYLITE_4.54.1.

• This upgrade introduced changes in the TaskEngine component, particularly in how time-zone values are validated while processing scheduled activities.

In the newer framework version, the scheduler performs stricter validation of time-zone values using the Java ZoneId API.

Some existing schedule entries in the database were configured with the abbreviated time-zone value EST. During schedule processing, the system attempts to resolve this value, but it fails to recognize it as a valid time-zone identifier and throws the following exception:

Unknown time-zone ID: EST

Solution

The MickeyLite team has updated the framework to handle the EST time-zone value.
