Launchpad pro mk3 script .Need some help

Hi !
I try to achive a custom script that will let me have on launchpad pro one column of pads assign to a specific track name on the live set .
The goal is to have 8 tracks with specific name that will expose their clips on the 8 column of the launchpad whatever their position in the liveset.
Like a navigation box but for tracks that are not side by side
I succeded with reaction to locate the track thanks to the excellent tutorial, detect if there are clips in the clips slots regarding the track name, Now i would like to light up the pad on the launchpad pro to let me have a feedback of where clips are .
And i am stuck .
I am here :
- The script loop the scenes regarding the track i want (with the right name).
- if the clip slot has a clip he put the scene number in a modifier 2

Then i created a last reaction to switch on the light of the corresponding pad
-The listeners is "m2 modifier was updated"
and the action in midi controller send midi velocity value to input.
I use the "get value ranges" so that when , for example, the clip slot 2 have a clip it will send a note 81 + 2 , witch it the third pad in the line , and a velocity value of 3, witch is the white color.
pad note value for the first line up is
81 , 82, 83, etc...

but it does not work . I have a log error "(Wk-LppMk3 set3) There's a problem with 'Action Block 1' in reaction 'Reaction 4' (from 'modifier - m2 modifier was updated' listener) >>
>> 'int' object has no attribute 'send_value'' '

the listener works perfectly if i don't use the action "midi controller - send midi velocit value to input" . I tested it with a log text that simply send me a "oui" ...And it works.

I put both the script and the controller script here, if someone can help me please?
Thanks !
