Error: The imagemagick convert command could not be executed - OVH

Alright, fixed it so far. Seems like the files ImageMagick was processing were way too big.
Adding to my files template:

create:
  width: 2560

made things way smoother.

I also added some stricter restrictions on files upload :

accept:
  extension: jpg, png, jpeg, gif, mp4
  maxsize: 2500000

create:
  width: 2560

Thanks.
