MediaWiki 1.39.0-rc.0: Fatal exception of type "TypeError"



Hello every body,

I just upgraded Mediaiki to version 1.39 on the website https://www.vbu-ffm.de/UntermainWiki/index.php/Hauptseite.

After installation via https://www.vbu-ffm.de/UntermainWiki/mw-config/index.php I got the error message:

[415f8c982325b1e0fde16358] 2023-04-26 15:42:13: Fataler Ausnahmefehler des Typs „TypeError“
=> Fatal exception of type "TypeError"

When I set $wgShowExceptionDetails in LocalSettings.php to 'true' then I get the following message:


[e539e46096fad38a067e9df0] /UntermainWiki/ TypeError: MediaWiki\Session\BotPasswordSessionProvider::__construct(): Argument #1 ($grantsInfo) must be of type MediaWiki\Permissions\GrantsInfo, array given, called in /.../UntermainWiki/vendor/wikimedia/object-factory/src/ObjectFactory.php on line 247

#8 /.../UntermainWiki/includes/WebStart.php(86): require_once(string)
#9 /.../UntermainWiki/index.php(44): require(string)
#10 {main}

I'm not that proficient with PHP.
Does anyone have an idea how I can still get MediaWiki to work?
