News 10.2.0 error message

I get this error message in the log:

Cannot retrieve value of undefined directive Core.LegacyEntityDecoder invoked on line 337 in file /var/www/nextcloud/apps/news/vendor/ezyang/htmlpurifier/library/HTMLPurifier/Lexer.php at /var/www/nextcloud/apps/news/vendor/ezyang/htmlpurifier/library/HTMLPurifier/Config.php#901

How can i reset the News App and delete all database entries?

Use the bug tracker for issue reports and search it before you post something because that issue was already reported (3rdparty lib issue)

Thanks for the feedback, I will look at.
