How to match a specific bloc of multiple lines?

[vctls]

I wish to match all lines in the following block and stop just before the last line that says Exception trace:

In PDOException.php line 20:
                                           
  [Doctrine\DBAL\Driver\PDO\PDOException]  
  There is no active transaction           
                                           

Exception trace:

I've tried multiple expressions that work elsewhere but not in the plugin.

The text is matched by lines:

Oh, OK. This works, thanks a lot!
So "multiline" just means it will affect everything from the matching line, and then I have to set a second expression to close the block?
