Checking again, deletion of the entry in the hash table is failing.

In older versions of kamailio, if I am not mistaken, i used:
  $sht(websocket=>$conid) = null;
but it seems in recent version null was replaced with $null (as if i use
null, kamailio will not start)
so I am using
    $sht(websocket=>$conid) = $null;
but it seems this doesn't work.
So, how do we currently delete an htable entry at config file?
