Getting an error message when trying to access module library

When I try to go to modules on the website I’m getting the following error:

MediaWiki internal error.

Original exception: [YWS2h_QONDnRG_0mMUJ7CwAAABM] 2021-10-11 22:11:19: Fatal exception of type “Error”

Exception caught inside exception handler.

Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.

Same. First time user here. Tried all different browsers, but this error comes up when attempting to access.

I’m looking into the problem now.

Try now. One of the packages on which our theme depends needed to be updated after MediaWiki was earlier this evening.

Yes, that worked for me. thanks.
