Autoware unable to use ray_ground_filter

Hello everyone, I am trying to use the ray_ground_filter of autoware and it used to work just fine but recently it stopped working and it displays this error :

[ERROR] [1576830223.077886525]: Failed transform from base_link to velodyne

I guess it means that the TF between base_link and velodyne is missing bt it seems very surprising.

And If I choose velodyne as the base_frame parameter of the ray_ground_filter it's simply not working.

Do you have an idea of whats wrong ?

Thanks a lot
