the news webpart in list and carousel mode doesn't show the news items that exist, unless you specify them explicitly using the "organize" function of web part.
What this means is that the most recently added webpart doesn't show up at the top of the "News webpart" list.
The news webpart gives "something went wrong" error.
Same error in IE and Chrome.
I thought it was caused by new news items with titles that contained maori characters e.g. Staff Announcements: Pānui Kaimahi - 22 Āperira 2020
BUT even when i rename the aspx files in PageFiles to remove the accents above the characters I still get the errors.
I've also seen the same sort of error when a users creating the news item was on a very slow connection.
In both cases the news item page works fine if you go to it specifically in the browser window. It is the filter or select statement in the News webpart that is having the problem.
Note the middle column of the home page is using the Modern Yammer web part. Could it be some cross over error ??
Please tell me how to find the news pages which are causing the issue, and how to fix it !

This is the error I'm getting with the News Web part
Something went wrong
If the problem persists, contact the site administrator and give them the information in Technical Details.

Hi, @Dorje McKinnon
I have the same error. I figure out that this problem happens when I have more than 8 "Managed metadata" fields. After I created another managed field, the "News Webpart" stop working if I have selected from"This site".
I need to selected from "This site" in order to use the filters by field properties, so, my unique options is not use more than 8 managed metadata fields.
I hope SharePoint could help us, increasing this limit.

The "Site pages" library where the news items are giving the news webpart error has:
7 Content types
These 7 content types mean we have 20 columns for this library
To try and get to the bottom of the issue I used ShareGate to migrate all my news items to another Teams SharePoint sitepages library. In that site collection they don't cause the error when using the Modern News Web parts.
In my Test Site collection SitePages library there are:
5 Content types
These 5 content types mean in the Test Site collection sitepages library we have 18 columns
In my live intranet, with the error. I'll try to remove one of the Managed Meta Data columns and see if that fixes the issue.
Thank you for suggesting I check this.

Ola @Dalejo ,
I removed one of my content types, and one of the columns in the library (managed metadata), so that I now have 7 managed metadata columns in my Intranet SitePages library.
I have a test home page with NO other web parts on it
When I add the News web part I get
Which seems to be the same as the error I was getting with 8 managed metadata columns.
For testing I set up another Site collection, with a site pages library, and I had copied all news items from the intranet to this test site pages library. Wen I create a test home page, with the news web part in it the test site pages news items load and display fine. If I change the test home page news webpart to use "Select sites" and choose the intranet, I get the same error as on the home page of the intranet.
Interestingly on the main intranet home page if I use "select news source" and choose the test site collection the news doesn't load and gives the same error (above).
So it seems the intranet site collection or sitepages library itself is the issue.
Anyone have suggestions on how I can track it down ?

And so eventually we've found a solution.
Two Search Schema managed properties with the same names or alias.
Thanks to Mike Lee (Boston) and his excellent post about how the Modern News Web part is reliant on search
Though my issue was different, I felt there might be something in what Mike Lee (Boston) had documented.
AND yes there was.
We too had a Search Managed Property called AuthorOWSUSER and another Managed property Refinablestring05 with the Alias of AuthorOWUSER.
After moving to SharePoint online, but before modern sharepoint search and news was available we had, as I know many organisations did and do, a customised search page with multiple filters. Refinablestring05 was used on that classic custom search page to provide an Author refiner to staff searching for specific content. We had done this because the search managed property Refinablestring05 could be set to Refine/Sort etc unlike the default AuthorOWSUSER managed property.
As modern search became available we found more value in it than maintaining our custom search page so we moved across to SharePoint online modern search, and all went well for 9 or 10 months until we started seeing the error outlined in this post.
As per Mike Lee (Boston) 's blog post, as soon as I had altered the name of Refinablestring05's alias to be different than managed property AuthorOWSUSER the news web parts started working fine.
So our issue wasn't due to Maori letters in file names, nor was it due to too many managed metadata columns (though they may cause issues in some situations), but due to search configuration.
Here is the Refinablestring05 managed search property after I renamed the Alias to AuthorOWSUSER1
Comment for Modern News Web part team and other Microsoft staff
I think that this issue is a classic example of assumptions not being true and testing being done with test data rather than real tenant setups. SharePoint has been around a long time, so organisations have lots of legacy settings (best practice at the time) which don't have an impact or are even remembered. Then with a small code change, and I couldn't find any mention of changes to the Modern News web part code, weird and non-useful errors are returned to the users.
Please - take a leaf from the OneDrive team's book and make EVERY error useful in that it tells the person who sees it what to do next.
