Error in AWAF v17.1 DoS Dashboard

Hi all,

I'm running v17.1.3.2 and provisioned for AWAF and LTM. After testing the DoS attack, the event had been detected. The issue is when I click on the Attack ID from the DoS Event Reporting, directing to DoS Dashboard, the Dashboard is showing the errors below and nothing is shown on the Attack Duration widget.

Tested this with previous version v17.1.1.3, it shows exactly the same errors.

Anyone had experienced this for AWAF with version 17.1? Are there any solutions for this.

Thank you.
