REST error Error with code -2147024891 - Creating News Post on SharePoint Online

[Richard Pickles]

I have started to get an error when trying to create a news post on a SharePoint online site, creating news posts on this site is nothing I haven't done many times before but now I am getting this error on all sites within our tenant. 

Below is the full error I get when I try to save the draft before publishing, or publishing. 

I've raised it with our IT Admin team but wanted to see if anyone else had suddenly started to get this message... I will post a follow up if I get word back on the issue.
