Null given error

Sophia

Hi to all the users!

Some of my users profile return this error calling for Discussions or Comments from theyr profile page:

Argument 1 passed to Vanilla\Formatting\FormatService::renderExcerpt() must be of the type string, null given, called in /home2/xxxxx/forum.xxxxx.com/applications/vanilla/views/discussion/profilecomments.php on line 29

and no way to list all of the post they did.

rel is 2021.011

Is that have to cast that null to a string? How to do that?

Please and Thanks in advance,

Sophia
