AGI Script Debuging

short version…
I have agi debuging enabled ( agi set debug on ) but $agi->conlog() does not do what it used to do…

long version…
I migrated from 12.x to 13.x ( I think I was at 12.x… not 100% sure )

I have some code in my script that I use for debuging…

        // display message in log ( if phpagi debug is enabled.
        function pr($data) 
        {
                global $agi;
               $RC = $agi->conlog(print_r($data,1));
                return $RC;
        }

I used to get things in the /var/log/asterisk/full that had something like:
AGI Object
(
[request] => Array
(
[agi_request] => callscreener.agi
[agi_channel] => Motif/+18175551212-da0a

[agi_version] => 13.8.0
[agi_callerid] => 8175551212
[agi_calleridname] => Daddy Cell
[agi_callingpres] => 0

)

    [config] => Array
        (
            [festival] => Array
                (
                    [text2wave] => /usr/src/festival/bin/text2wave
                    [tempdir] => /var/lib/asterisk/sounds/tmp/
                )

            [phpagi] => Array
                (
                    [error_handler] => 1
                    [debug] => 
                    [admin] => 
                    [tempdir] => /tmp
                )

        )

    [asmanager] => 

.
.
.
which is a result of:
$agi->conlog(print_r($data,1));

now with 13.x ( latest ) and agi set debug on
I only get:

pbx.c: Executing [[email protected]:2] AGI("Motif/+18175551212-da0a", "callscreener.agi") in new stack

res_agi.c: <Motif/+18176017338-da0a>AGI Tx >> agi_calleridname: Daddy Cell

… so I ‘see’ the effect of agi set debug on… BUT I don’t get the
$agi->conlog()
executing like it used too.

What am I missing. I vaguely recall a web page setting for the agi debug stuff on or off with the older version of freepbx but I can’t find that any more.
