[midPoint] click Server tasks shows "Failed to convert query. Reason: Attempt to store multiple values in single-valued property handlerUri"

[Hsin-Fang Hsu]

Hi,

I have midpoint 4.4.1 running on the system.
The error shows up whenever I click anything related to task (click “Server tasks”, select tasks in the repository objects, click defined tasks in resources).
As I cannot read the tasks from the GUI (500 error), I used midpoint restApi to download all tasks. None of the task have more than one <handlerUri>.

Here is the 500 error when I click task related:

Here is the detailed logs from the error.
