Can you add compability for these mod:
https://mods.factorio.com/mods/mickael9/portable-chests

when i try to start with it i got an error:

Or if error is cause from these mod side can you show when i should to insert these comand:
"Commands for modders:
omni.compression.exclude(recipe): Maakes it so compression will skip over this recipe if the modder feels it is neccisery."?

I'll look into the cause

If you want a quick fix, the place to put it is before data-final-fixes, so data-updates work.

I tried adding lines:
Omni.compression.exclude (wooden-chest):
Omni.compression.exclude (iron-chest):
Omni.compression.exclude (steel-chest):

or Omni.compression.exclude (portable-chests):

At the beginning/end of the file data-final-fixes.lua of portable chests mod and Omnicompression mod, but anyway got an startup error. I'm probably doing something wrong for lack of competence.
