Error in News webpart with managed metadata property filter

Hi,

The News web part is not displaying news pages when I select sites and filter on a managed property.

I am using the News web part to show "Important news" pages from selected sites (around 35 sites) in the tenant. I have added a custom column for important news in the site pages library across all communication sites.

In the web part properties, I have set a filter criteria where I selected the 'Important news' managed property to display in the web part.

The web part was functioning perfectly until yesterday, and it hasn't been changed for a few months. Today, the web part is showing an error: "The maximum query template length has been exceeded. The maximum length is 4096 characters." I am aware that the text length for queries using Keyword Query Language is 4096 characters.

Upon further troubleshooting in the browser console, I noticed that the web part is generating a very long QueryTemplate, as shown below.

 

Did Microsoft change the way QueryTemplate is built? Some IDs are repeating and seem unnecessary.
